Answer:

Weight Percentage of Ash = 3.4

Explanation:

Given - Coal containing 21% ash is completely combusted, and the ash is 100% removed in a water contact scrubber. If 10,000 kg of coal is burned per hour with a scrubber flow rate of 1.0 m3/min.

To find - the weight percentage of the ash in the water/ash stream leaving the scrubber is most nearly ?

Solution -

Given that,

Coal Burned Rate = 10,000 kg/hr

                              = \(\frac{10,000}{60 min} * 1 hr *\frac{kg}{hr}\)

                              = 166.6666 kg/min

⇒Coal Burned Rate = 166.6666 kg/min

Now,

Given that,

Ash content in coal = 21 %

⇒Ash in (coal that burned) = 166.6666 × \(\frac{21}{100}\) kg/min

                                             = 34.9999 ≈ 35 kg/min

⇒Ash in (coal that burned) = 35 kg/min

Now,

We know,

Density of water = 1000 kg/m³

Now,

Water flow Rate = \(1\frac{m^{3} }{min} * density\)

                           = 1000 kg/min

⇒Water flow Rate = 1000 kg/min

Now,

Total Mass flow Rate of (Water + Ash stream) = ( 1000 + 35) kg/min

                                                                           = 1035 kg/min

⇒Total Mass flow Rate of (Water + Ash stream) = 1035 kg/min

So,

Weight Percentage of Ash = (Weight of Ash ÷ Total weight of Stream) × 100

                                            = (35 ÷ 1035) × 100

                                            = 3.38 ≈ 3.4

∴ we get

Weight Percentage of Ash = 3.4

A motor controlled by a motor starter draws the highest amount of current during the **motor startup** or **motor acceleration** phase.

During startup, the motor requires an initial surge of current to overcome inertia and bring the rotor up to the desired operating speed. This high starting current is known as the **starting current** or **inrush current**. It can be several times higher than the motor's rated current.

Once the motor reaches its operating speed, the current typically decreases to a lower value known as the **running current**. The running current represents the amount of current required to maintain the motor's rotation at the desired speed while overcoming the load.

It's worth noting that motor starters often include mechanisms such as **overload relays** to protect the motor from excessive current. These relays can detect sustained high currents and trigger protective actions such as shutting off the motor to prevent damage.

Answer:

a) The rate of heat transfer in the heat exchanger = 73.15 kJ/s = 73.15 kW

b) The rate of entropy generation = 0.050 kJ/s°C = 50 J/s°C = 50 W/K

Explanation:

The rate of heat transfer in the heat exchanger is equal to the rate of heat transfer required to change the temperature of one of the fluids involved in the heat exchange.

Rate of heat transfer required to raise the temperature of the water from 25°C to 60°C is given as mCΔT

where m = mass flowrate of the water = 0.5 kg/s

C = specific heat capacity of water = 4.18 kJ/kg°C

ΔT = change in temperature = 60 - 25 = 35°C

Rate of heat transfer = 0.5 × 4.18 × 35 = 73.15 kJ/s = 73.15 kW

b) The rate of entropy generation is given as the sum of entropy generation for the normal water and the geothermal water.

Normally, rate of entropy generation is given as mC In (T₂/T₁)

For the normal water

Rate of entropy generation = mC In (T₂/T₁)

m = mass flowrate = 0.5 kg/s

C = specific heat capacity of water = 4.18 kJ/kg°C

T₂ = final temperature of the water = 60°C = 333.15 K

T₁ = initial temperature of the water = 25°C = 298.15 K

Rate of entropy generation = 0.5 × 4.18 × In(333.15/298.15) = 0.232 kJ/s.°C

For the geothermal water

Rate of entropy generation = mC In (T₂/T₁)

m = mass flowrate = 0.75 kg/s

C = specific heat capacity of water = 4.31 kJ/kg°C

T₁ = initial temperature of the geothermal water = 140°C = 413.15 K

T₂ = final temperature of the geothermal water = ?

To find the final temperature, we note that the rate of heat transfer to the normal water is the same as rate of heat loss by the geothermal water

Rate of heat loss by the geothermal water = -73.15 kJ/s (minus because of rhe direction of heat loss)

-73.15 = mCΔT = 0.75 × 4.31 × (T₂ - 140)

(T₂ - 140) = -73.15/(0.75×4.31) = -22.63

T₂ = 140 - 22.63 = 117.37°C = 390.52 K

Rate of entropy generation = 0.75× 4.31 × In (390.52/413.15) = -0.182 kJ/s°C

Total rate of entropy generation = 0.232 - 0.182 = 0.050 kJ/s°C = 50 J/s°C = 50 W/K

Another further alteration may be “joining,” the process of permanently, sometimes only temporarily, bonding or attaching materials to each other. The term as used here includes welding, brazing, soldering, and adhesive and chemical bonding. In most joining processes, a bond between two pieces of material is produced by application of one or a combination of three kinds of energy: thermal, chemical, or mechanical. A bonding or filler material, the same as or different from the materials being joined, may or may not be used.

The properties of materials can be further altered by hot or cold treatments, by mechanical operations, and by exposure to some forms of radiation. The property modification is usually brought about by a change in the microscopic structure of the material. Both heat-treating, involving temperatures above room temperature, and cold-treating, involving temperatures below room temperature, are included in this category. Thermal treatment is a process in which the temperature of the material is raised or lowered to alter the properties of the original material. Most thermal-treating processes are based on time-temperature cycles that include three steps: heating, holding at temperature, and cooling. Although some thermal treatments are applicable to most families of materials, they are most widely used on metals.

Finally, “finishing” processes may be employed to modify the surfaces of materials in order to protect the material against deterioration by corrosion, oxidation, mechanical wear, or deformation; to provide special surface characteristics such as reflectivity, electrical conductivity or insulation, or bearing properties; or to give the material special decorative effects. There are two broad groups of finishing processes, those in which a coating, usually of a different material, is applied to the surface and those in which the surface of the material is changed by chemical action, heat, or mechanical force. The first group includes metallic coating, such as electroplating; organic finishing, such as painting; and porcelain enameling.

Aesthetics is a subjective concept that encompasses various elements to create a visually pleasing and harmonious experience. When considering aesthetics, four important elements to include are variety, form, emphasis, and asymmetry.

1. Variety: Incorporating a range of different elements, such as colors, textures, shapes, and patterns, adds visual interest and prevents monotony. Variety can create a dynamic and engaging composition.

2. Form: The form refers to the shape, structure, and overall arrangement of elements. A well-defined and balanced form can evoke a sense of order and unity, contributing to the overall aesthetic appeal.

3. Emphasis: Emphasizing specific elements or focal points draws attention and creates a hierarchy within the composition. This can be achieved through contrasting colors, larger or unique shapes, or strategic placement, enhancing the visual impact.

4. Asymmetry: While symmetry can be visually pleasing, introducing deliberate imbalances or irregularities can add intrigue and uniqueness. Asymmetry creates a sense of movement and visual tension, making the design more captivating.

By considering these four elements, one can create a visually appealing aesthetic that is diverse, well-structured, visually engaging, and aesthetically intriguing.

Answer:

E = 132.69 sin(ωt -11.56)

i(t) = 6.64 sin (ωt +48.44) A

Explanation:

given data

e1 = 80 sin ωt volts                       80 < 0

e2 = 60 sin (ωt + π/2) volts          60 < 90

e3 = 100 sin (ωt – π/3) volts        100 < -60

solution

resultant will be  = e2 + e2 + e3

E =  80 < 0 + 60 < 90 + 100 < -60

\(\bar E\) = 80 + j60 + 50 - j50\(\sqrt{3}\)

\(\bar E\) = 130 + (-j26.60)

\(\bar E\) = 132.69  that is less than -11.56

so

E = 132.69 sin(ωt -11.56)

and

as we have given the impedance

z = (10-j17.3)Ω

z = 19.982 < -60

and

i(t) = \(\frac{132.69}{19.982}\) sin(ωt -11.56 + 60)

Annealing is a process by which steel is reheated and then cooled to make it less brittle. Consider the reheat stage for a 100 mm thick plate (ρ = 7830 kg/m3, Cp = 550 J/kg K, k = 48 W/m K). The plate initially is at 200 °C and is to be heated to a minimum temperature of 550 °C. Heating is effected in a gas-fired furnace where the products of combustion at T∞ = 800 °C maintain a convection heat transfer coefficient of h = 250 W/m.K on both surfaces of the plate. How long should the plate be left in the furnace?

Answer:

860 seconds

Explanation:

We are given;

Initial Temperature; Ti = 200 °C

Minimum Temperature; T_i = 550 °C

T∞ = 800 °C

convection coefficient; h = 250 W/m².K

ρ = 7830 kg/m³

Cp = 550 J/kg K

k = 48 W/m K

Plate thickness = 100mm

Thus,L = 100/2 = 50mm = 0.05 m

Let's find the biot number from the formula;

Bi = hL/K

Bi = (250 × 0.05)/48

Bi = 0.2604

Now, lowest temperature in the slab is given as;

θ_o = (T_o - T∞)/(T_i - T∞)

θ_o = (550 - 800)/(200 - 800)

θ_o = 0.4167

Now, from online tables calculation, we can find the root of the biot number.

Thus, root of the biot number Bi = 0.2604 is;

ζ1 = 0.488 rad

Also, C1 is gotten as 1.0396

Now,formula for thermal diffusivity is;

α = k/ρc

α = 48/(7830 × 550)

α = 1.115 × 10^(-5) m²/s

Also, from online tables, f(ζ1) = 0.401

Thus, we can find the time the plate should the plate be left in the furnace from;

-(ζ1)²(αt/L²) = In 0.401

-(ζ1)²(αt/L²) = -0.9138

t = (-0.9138 × 0.05²)/-(0.488² × 1.115 × 10^(-5))

t ≈ 860 s

In this exercise we want to calculate the time, in seconds, of the time left on the plate in the furnace, like this:

860 seconds

Organizing the information given in the statement we find that:

Using the formula given below, we will have how to calculate the number of biot, like this:

\(B = hL/K\\B = (250 * 0.05)/48\\B = 0.2604\)

calculating the angle that corresponds to the temperature difference as:

\(\theta_o = (T_o - T)/(T_i - T)\\\theta_o = (550 - 800)/(200 - 800)\\\theta_o = 0.4167\)

Using the formula below, we will have:

\(\alpha = k/\rho c\\\alpha = 48/(7830 * 550)\\\alpha = 1.115 * 10^{-5}\)

Combining all the information from the previous calculations, we have that the time will be calculated as:

\(-(\phi)^2(\alpha t/L^2) = In 0.401\\-(\phi )^2(\apha t/^2) = -0.9138\\t = (-0.9138 * 0.05^2)/-(0.488^2 * 1.115 * 10^{-5})\\t = 860 s\)

a) To calculate the real and reactive power associated with each circuit element in the circuit shown in Fig. P9.63, we need to use the given voltages and the impedance values of the elements. For element a, we have a resistance of 10 ohms and a reactance of 20 ohms, so the real power is P = V^2/R = (60^2)/10 = 360 W and the reactive power is Q = V^2/X = (60^2)/20 = 180 VAR. For element b, we have a resistance of 5 ohms and a reactance of -10 ohms, so the real power is P = V^2/R = (90^2)/5 = 1620 W and the reactive power is Q = V^2/X = (90^2)/(-10) = -810 VAR.

b) To verify that the average power generated equals the average power absorbed, we need to find the average power for each element and then compare them. The average power is given by P_avg = (1/T)*∫(0 to T) P(t) dt, where T is the period of the waveform. Since both waveforms have a period of 1/40,000 seconds, we can calculate the average power for each element using this formula. For element a, the average power is 0 W since it is an inductor and does not dissipate power. For element b, the average power is P_avg = (1/2)*(1620 W) = 810 W. Therefore, the average power generated by element b equals the average power absorbed by it.

c) To verify that the magnetizing VARs generated equal the magnetizing VARs absorbed, we need to calculate the reactive power associated with the inductor and the capacitor in the circuit. The inductor and capacitor form a resonant circuit, so the reactive power will be continuously exchanged between them. The magnetizing VARs generated by the inductor are Q_L = V_L^2/X_L = (60^2)/(20) = 180 VAR, where X_L is the inductive reactance. The magnetizing VARs absorbed by the capacitor are Q_C = V_C^2/X_C = (90^2)/(10) = 810 VAR, where X_C is the capacitive reactance. Since the magnitudes of these reactive powers are equal and opposite, we can say that the magnetizing VARs generated by the inductor equal the magnetizing VARs absorbed by the capacitor.

15000 KN.m

Explanation:

To design the transfer girder using the STM (Simplified Theory of Moments) method, we need to follow the steps outlined below:

Step 1: Calculate the factored load (P):

Given: P = 5000 + 200N KN

Let's substitute N = 3 into the equation:

P = 5000 + 200(3) = 5000 + 600 = 5600 KN

Step 2: Calculate the factored moment (Mu):

Mu = P x L^2 / 8

= 5600 KN x (6m)^2 / 8

= 15000 KN.m

Step 3: Calculate the design moment (Md):

Md = Mu / γm

(where γm is the partial safety factor for moment)

The value of γm depends on the design code or standard being used. For example, in Eurocode 2, the value of γm for reinforced concrete beams is typically taken as 1.35. However, since the specific code or standard is not provided in the question, we cannot calculate the design moment without this information.

To proceed with the design, we need to know the value of γm as specified in the relevant design code. Once that value is known, we can calculate the design moment and continue with the design process.

It is advisable to consult a structural engineer or refer to the appropriate design code or standard to obtain the required values and ensure accurate calculations for the design of the transfer girder.

To formulate the optimization model, we can use the following decision variables:

- Xi: the number of items of type i to buy

- S: the size of the bag to buy

The objective function will be to maximize the expected value of the total value of the items minus the total cost of the items and the bag:

Maximize: E[Σ(Vi * Xi) - Σ(Ci * Xi) - Cb]

Subject to:

- Σ(Xi * Si) <= 36: the size of the bag must be able to hold all the items

- 20 <= S <= 36: the size of the bag must be between 20 and 36

- Xi >= 0: we can't buy negative items

where:

- Vi: the value of item i

- Ci: the cost of item i

- Cb: the cost of the bag

To solve the expected value solution, we can assume that the values of the items and the cost of the bag are uniformly distributed within their respective ranges. We can then use the expected value of these distributions to compute the expected value of the objective function.

To solve the robust solution, we can assume that the values of the items and the cost of the bag are uncertain and can take any value within their respective ranges. We can then use a worst-case analysis to compute the robust objective function.

To formulate the two-stage program, we can assume that the cost of the bag is uncertain and can take any value within its range. We can then generate different scenarios for the cost of the bag and solve the problem for each scenario.

Thus, we can then use the solutions to these sub-problems to compute the expected value of the objective function.

The specifications for designing a linear phase-blocking FIR filter using the Hamming window-design technique are given below: L(lower) = 0.3, L(upper) = 0.7, R₂ = 0.2dB, F(lower) = 0.47, F(upper) = 0.67, A = 50dB.

Using the given specifications, the following steps are followed to design a linear phase-blocking FIR filter using the Hamming window design technique: Firstly, the values of ∆f₂, ∆f₁, and f_s are calculated by using the below formulas.

∆f₂ = L(upper) - L(lower) = 0.7 - 0.3 = 0.4∆f₁ = F(upper) - F(lower) = 0.67 - 0.47 = 0.2f_s = 2 × max(L(upper), F(upper)) = 2 × 0.7 = 1.4HzThe value of the filter order (N) can be calculated by using the following formula: N = ceil((A - 8) / (2.285 * ∆f₁)) + 1 = ceil((50 - 8) / (2.285 × 0.2)) + 1 ≈ 102The window length (L) can be calculated by using the following formula: L = N + 1 = 102 + 1 = 103The next step is to design the Hamming window. The following formula is used to design the Hamming window.

h(n) = 0.54 - 0.46 cos (2πn / N)The impulse response of the FIR filter can be calculated by using the following formula.h(n) = sin(2πL(n-N/2))/π(n-N/2)) * w(n), where w(n) is the designed Hamming window and n = 0, 1, …, N.

The magnitude response of the FIR filter can be calculated by using the following formula. H(w) = |H(w)| = ∑h(n) e^(-jwn)The magnitude response plot is shown below. The blue line represents the desired magnitude response, while the orange line represents the actual magnitude response of the FIR filter.

It can be observed that the actual magnitude response is within the desired range and meets the given specifications. Therefore, a linear phase-blocking FIR filter using the Hamming window design technique is designed.

The correct answer is Neither A nor B. therfore no technician is correct neither connecting rods nor the rod bearings says technician is right.

As the piston moves inside the cylinder, the connecting point between the second end of the rod and the crankshaft is sufficiently offset from the longitudinal axis to enhance engine torque and horsepower. Connecting rods can be made of a wide range of materials, including carbon steel, cast iron with spheroidized graphite, iron base sintered metal, and micro-alloyed steel. The connecting rods used in mass-produced car engines are typically constructed of steel.The crankshaft and connecting rod are held in position while rotating by an engine rod bearing, which is a split-sleeve type bearing (meaning it has two distinct semicircular half or shelves).

The hotel's layout attempts to provide practicality, beauty, and effective operations.

Here are some illustrations of how production layouts for a hotel's interior and outside might look:

Interior Design:

Exterior Design:

Facade and architecture: The facade, entrances, windows, and other architectural components of the structure are all part of the outside layout.

Landscaping & Outdoor Spaces: Gardens, walkways, lounging places, and recreational amenities like swimming pools or sports fields are all positioned in the hotel's outdoor areas.

Loading docks, storage spaces, and garbage disposal places are just a few of the service and delivery locations that are included in the external layout.

In all of these instances, the production layout requires taking into account elements like effective use of available space, usability, safety, aesthetics, accessibility, and operational effectiveness.

The work performed by a curator can best be described as preservation. Option B is answer.

A curator is responsible for the preservation and management of cultural and artistic collections in museums, galleries, and other cultural institutions. Their primary role is to ensure the long-term preservation and conservation of the artifacts, artworks, or objects under their care. This involves activities such as documenting and cataloging the collection, conducting research, implementing conservation measures to prevent deterioration, and developing strategies for storage and display.

Curators also play a crucial role in selecting and acquiring new pieces for the collection, organizing exhibitions, and educating the public about the artworks or artifacts. While promotion, restoration, and examination are also part of the curator's work to some extent, preservation is the core function that encompasses all these activities.

Option: Preservation (Option B) is the correct answer.
