The accurate measurement reported by the graduated cylinder is the milliliter.

Explanation: The milliliter (mL) measurement on a graduated cylinder represents the volume of liquid contained within the cylinder. Each marking on the cylinder corresponds to an increment of one milliliter, allowing for precise measurement of liquid volumes. The graduated cylinder is designed with a narrow cylindrical shape to ensure accurate readings. When measuring a liquid, you read the volume by aligning the bottom of the meniscus (the curved surface of the liquid) with the nearest milliliter marking. The milliliter is a unit of volume in the metric system and is equal to one-thousandth of a liter. It is commonly used in scientific experiments and various laboratory settings.

Answer:

\(W_s =\) 283.181 hp

Explanation:

Given that:

Air enters a compressor operating at steady state at a pressure \(P_1\) =  176.4 lbf/in.^2  and Temperature \(T_1\) at 260°F

Volumetric flow rate V = 424 ft^3/min

Air exits at a pressure \(P_2\)  = 15.4 lbf/in.^2 and Temperature \(T_2\) at 80°F.

Heat transfer occurs at a rate of 6800 Btu/h from the compressor to its surroundings; since heat is released to the surrounding; then:

\(Q_{cv}\) = -6800 Btu/h  = - 1.9924 kW

Using the steady  state  energy in the process;

\(h_2 - h_1 + g(z_2-z_1)+ \dfrac{1}{2}(v^2_2-v_1^2) = \dfrac{Q_{cv}}{m}- \dfrac{W_s}{m}\)

where;

\(g(z_2-z_1) =0\)  and  \(\dfrac{1}{2}(v^2_2-v_1^2) = 0\)

Then; we have :

\(h_2 - h_1 = \dfrac{Q_{cv}}{m}- \dfrac{W_s}{m}\)

\(h_2 - h_1 = \dfrac{Q_{cv} - W_s}{m}\)

\({m}(h_2 - h_1) ={Q_{cv} - W_s}\)

\(W_s ={Q_{cv} + {m}(h_2 - h_1)\) ----- (1)

Using the relation of Ideal gas equation;

P₁V₁ = mRT₁

Pressure \(P_1\) =  176.4 lbf/in.^2   = ( 176.4 ×  6894.76 ) N/m² = 1216235.664 N/m²

Volumetric flow rate V = 424 ft^3/min = (424 ×  0.0004719) m³  /sec

= 0.2000856 m³  /sec

Temperature = 260°F = (260°F − 32) × 5/9 + 273.15 = 399.817 K

Gas constant R=287 J/kg K

Then;

1216235.664 N/m² × 0.2000856 m³  /sec = m × 287 J/kg K × 399.817 K

\(m = \dfrac { 1216235.664 N/m^2 \times 0.2000856 m^3 /sec } {287 J/kg K \times 399.817 K }\)

m = 2.121 kg/sec

The change in enthalpy:

\(m(h_1-h_2) = m * C_p * \Delta T= m* C_p * ( T_1 -T_2)\)

\(= 2.121* 1.005* ( 399.817 -299.817)\)

= 213.1605 kW

From (1)

\(W_s ={Q_{cv} + {m}(h_2 - h_1)\)

\(W_s =\)  - 1.9924 kW + 213.1605 kW

\(W_s =\) 211.1681  kW

\(W_s =\) 283.181 hp

The power input is \(W_s =\) 283.181 hp

The energy transferred between objects at different temperatures is called heat. Heat is a form of energy that flows spontaneously from hotter objects to cooler objects until thermal equilibrium is achieved. This transfer of energy occurs due to the difference in temperature between the two objects and the thermal energy stored within them.

Thermal energy refers to the total energy stored within a substance due to the motion of its atoms and molecules. When two objects of different temperatures are brought into contact, the atoms and molecules in the hotter object transfer some of their thermal energy to the cooler object through the process of heat transfer.

In truss analysis, a negative member axial force suggests that the member or the joints at its ends are in compression, whereas a positive member axial force suggests that they are in tension.

A tension member is subject to forces that pull outward at its ends on truss bridges. These members are frequently individual metal elements, such as bars or rods, even on a “wooden” truss bridge.

Compressive forces are heavier and push or compress together. The parts come together to form a triangle.

Therefore, A rigid structure called a truss is made up of two force members—where forces are applied only twice—that link at joints and are subject to external forces.

At 1.2mpa pressure and 50c

What is pressure?
By pressing a knife against some fruit, one can see a straightforward illustration of pressure. The surface won't be cut if you press the flat part of the knife against the fruit. The force is dispersed over a wide area (low pressure).

a)Mass flow rate of the refrigerant
Therefore h1= condenser inlet enthalpy =278.28KJ/Kg
saturation temperature at 1.2mpa is 46.29C
Therefore the temperature of the condenser

T2 = 46.29C - 5
T2 = 41.29C

Now,
d)power consumed by compressor W = 3.3KW
Q4 = QL + w = Q4
QL = mR(h1-h2)-W
= 0.0498 x (278.26 - 110.19)-3.3
=5.074KW
Hence refrigerator load is 5.74Kg

(COP)r = 238/53

Answer:

12 mins

Explanation:

The summation of the forces in vertical direction

= Fb - Fd - w = 0 ∴ Fd = Fb - w  ----- ( 1 )

Fb ( buoyant force ) = Pair * g * Vballoon ------- ( 2 )

Pair = air density , Vballoon = volume of balloon

Vballoon = \(\frac{\pi D^3}{6}\) ,  where D = 4  ∴  Vballoon = 33.51 ft^3

g = 32.2 ft/s^2

From property tables

Pair = 2.33 * 10^-3 slug/ft^3

μ ( dynamic viscosity ) = 3.8 * 10^-7 slug/ft.s

Insert values into equation 2

Fb = ( 2.33 * 10^-3 ) * ( 32.2 ) *( 33.51 )  = 2.514 Ib

∴ Fd = 2.514 - 2.5 = 0.014 Ib ( equation 1 )

Assuming that flow is Laminar  and  RE < 1

Re = (Pair * vd) / μair   -------- ( 3 )

where:  Pair = 2.33 * 10^-3 slug/ft^3 ,  vd = ( 987 * 4 ) ft^2/s ,   μair = 3.8 * 10^-7 slug/ft.s

Insert values into equation 3

Re = 2.4 * 10^7 (  this means that the assumption above is wrong )

Hence we will use drag force law

Assume Cd = 0.5

Express  Fd using the relation below

Fd = 1/2* Cd * Pair * AV^2

therefore V = 1.39 ft/s

Recalculate  Reynold's number using  v = 1.39 ft/s

Re = 34091

from the figure Cd ≈ 0.5 at Re = 34091  

Finally calculate the rise time ( time taken to reach an altitude of 1000 ft )

t = h/v

Answer:

a) 3.2279 kmol/min

b) 0.3407 kmol/min

c)  0.1148

Explanation:

molecular weight of Benzene = 78

molecular weight of cyclohexane = 84

mass flow rate of the feed = 500kg/min

molecular weight of mixture = 0.55 Mb + 0.45 Mc

Mmix = 0.55 ( 78 ) + 0.45 ( 84 ) = 80.7

Given that The molar flow rate of mixture feed ( F ) = 6.195 kmol/min

Molar flow rate of Benzene in the feed = 6.195 * 055 = 3.4072kmol/min

a)Determine the Distillate flow rate

Molar flow rate of Benzene in distillate = 0.9 * 3.4072 = 3.0665 kmol/min

mol % of Benzene in distillate = 0.95

therefore the molar flow rate of Distillate = 3.0665 / 0.95 = 3.2279 kmol/min

b)Determine the Bottom flow rate

molar flow rate of Benzene in the Bottom = 3.4072 - 3.0665 = 0.3407 kmol/min

c) composition of the bottoms  product in mole %

composition of the bottoms product in mole %. = molar flow rate of Benzene in the Bottom / overall mol balance

overall mol balance ( w ) = F - D  = 6.195 - 3.2279 = 2.967 kmol/min

composition of the bottoms product in mole %. = 0.3407 / 2.967 = 0.1148

To help you simplify the given rational expression using the provided terms. The expression is:

\(\frac{n^2+5n-24}{n^2-11n+24}\)

Step 1: Factor the numerator and the denominator.
To do this, we look for two numbers that multiply to the constant term and add to the coefficient of the linear term.

Numerator: \(n^2+5n-24\)
Factors: (n - 3)(n + 8), because (-3) * 8 = -24 and (-3) + 8 = 5.

Denominator: \(n^2-11n+24\)
Factors: (n - 3)(n - 8), because (-3) * (-8) = 24 and (-3) - 8 = -11.

Step 2: Rewrite the expression with the factored terms.
\(\frac{(n - 3)(n + 8)}{(n - 3)(n - 8)}\)

Step 3: Cancel out the common factors.
Since (n - 3) is in both the numerator and the denominator, we can cancel it out.

\(\frac{\cancel{(n - 3)}(n + 8)}{\cancel{(n - 3)}(n - 8)}\)

Step 4: Write the simplified expression.
\(\frac{n + 8}{n - 8}\)

So, the simplified rational expression is \(\frac{n + 8}{n - 8}\).

Check: Evaluate the results against objectives and identify deviations. Act: Adjust and refine the plan based on the evaluation. Repeat the cycle to continuously improve processes.

The PDCA cycle begins with planning, where objectives are set and a plan is developed. Next is the implementation stage, where the plan is executed on a small scale. The check phase involves evaluating the results and comparing them with the objectives to identify any deviations or gaps. In the act phase, necessary adjustments and refinements are made to the plan based on the evaluation.

Answer:

A) L = 0.388 μm

B) D = 3.78 mm

Explanation:

We are given;

Characteristics impedance; Z_o = 75 ohms

Nominal capacitance; C = 69pF/m = 69 × 10^(-12) F/m

dielectric constant; k = 2.23

Inner diameter of conductor; d = 0.584 mm

A) Now formula for Characteristics impedance is given as;

Z_o = √(L/C)

Where L is the inductance per metre.

Making L the subject, we have;

L = (Z_o)²C

L = 75² × 69 × 10^(-12)

L = 0.388 × 10^(-6) m

L = 0.388 μm

B) To get the outer diameter, we will use the formula;

Z_o = (138/√k) log(D/d)

Where;

D is outer diameter.

Thus, Plugging in the relevant values;

75 = (138/√2.23) × log (D/0.584)

log (D/0.584) = 0.81158611538

(D/0.584) = 10^(0.81158611538)

D/0.584 = 6.48016576435

D = 6.48016576435 × 0.584

D = 3.78 mm

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
