Answer:

Q = 0.042 ft^3/s

Explanation:

Given data

pressure drop = 1 psi ( p1 -p2) =

Gasoline density = 1.32 slugs/ft^3

viscosity = 3.26 8 10^-3 Ibf.s/ft^2

correct viscosity of gasoline = 6.5 *10^-6 Ibf.s/ft^2

e = 0.0004 ft

assumptions

Since The base is of constant diameter then V1 = V2

also z1 = z2

therefore the steady  flow  energy equation will be

hf = pressure drop / ( gasoline density * g ) ------ equation 1

hf = head loss due to friction

g = 32.174 ft/s^2

equation 1 becomes

note : 1 ibf = slug ft / s^2

hf = \(\frac{1 (ibf/in^2) * 144 (in^2/ft^2)}{1.32 * 32.174}\)  = 3.4 ft

Volume flow rate can be obtained through iteration process using (hf)

therefore hf can be expressed as

hf = f * l/d * v^2/2g

fv^2 = hf * d/l * 2g ------------- equation 2

d = 1/12 (ft)

l = 10 (ft )  

g = 32 .174 ft/s^2

insert the following values into equation 2

fv^2 = 1.823 (ft^2/s^2) -------------- equation 3

assuming full turbulent flow

e/d = 0.0004 / (1/12) = 0.0048 ft  and

assuming Reynolds number ( re ) = 10^8

therefore from Moody's chart ; f = 0.03

insert ; f = 0.03 into equation 3

v = \(\sqrt{\frac{1.823}{0.03} }\)  = 7.8 ft/s

Now we have V = 7.8 ft/s  then we have to calculate for Reynolds number

Re = Pvd / u

u = viscosity of  gasoline

Re  = 1.32 * 7.8 * (1/12) / (6.5 *10^-6)

Re = 1.32 * 10^5

hence at this Reynolds number the value of ; f = 0.031 as gotten when we assumed the Reynolds number

v  = \(\sqrt{\frac{1.823}{0.031} }\)  = 7.67 ft/s

therefore the Volumetric flow rate

= Q = \(\frac{\pi d^2 }{4} * v\)

Q = \(\frac{\pi }{4} * (1/12)^2 * 7.67\)  = 0.042 ft^3/s

The key features of each house make them hurricane resistant by providing strength and stability against high winds, debris, and flooding. The reinforced concrete walls and roof of a concrete house, the steel frame of a steel house, and the timber frame covered with structural panels of a timber frame house all provide excellent protection during a hurricane.

Here are the key features of each house and how they make them hurricane resistant:

1. Concrete house: The main feature of a concrete house is its reinforced concrete walls and roof. This means that it is designed to withstand high winds, debris, and even floods. The foundation is also made of concrete, which helps prevent the house from shifting or sinking during flooding or high winds. The windows and doors are usually made of impact-resistant glass, which can withstand debris flying at high speeds during a hurricane.

2. Steel house: The key feature of a steel house is its frame. The frame is made of steel, which is incredibly strong and can withstand high winds and debris. The steel frame is bolted to a concrete foundation, which adds even more stability to the house. The walls and roof are usually made of metal panels, which are lightweight but very durable. The windows and doors are also impact-resistant and are usually made of laminated glass.

3. Timber frame house: Timber frame houses are built with a frame made of timber, which is then covered with structural panels made of materials like OSB or plywood. This provides a very sturdy and stable structure. The roof is usually made of metal panels, which are lightweight but very durable. The windows and doors are also impact-resistant and are usually made of laminated glass.

A and B are both valid technologies. Current flow is the term used to describe the movement of electrons in a circuit. It is measured in amperes (amps).

Electric current, whose strength is expressed in amps, is produced when electrons move through a circuit. From the power source to the resistor and back to the power source, the conductor travels in a circle. The current of electrons in the conductor is circulated across the circuit by the power source.

An example of this is a current. From a wire's negative to positive end, electrons flow through it. The difference in potential energy between the two electrodes in an electrochemical cell causes current to flow from the anode to the cathode externally in a galvanic cell.

The logic is ...

  out = ((b2·b0)' + b1)'

  out = b2·b1'·b0

Answer:

The answer is below

Explanation:

Given:

kg (glass) = 0.78 W/m⋅K, ka (air) = 0.026 W/m⋅K, h1 = 10 W/m2⋅K, h2 = 25 W/m2⋅K, glass length = Lg = 3 mm = 0.003 m, Lo = 3 mm = 0.003 m, La = 12 mm = 0.012 Height = 1.5 m, width = 2.4 m, room temperature = T = 20°C. Therefore:

Total resistance per unit area is given as:

\(R"=\frac{1}{h_1}+\frac{L_g}{k_g}+\frac{L_a}{k_a} +\frac{L_o}{k_g}+\frac{1}{h_2} \\\\R"=\frac{1}{10}+\frac{0.003}{0.78}+\frac{0.012}{0.026} +\frac{0.003}{0.78}+\frac{1}{25} \\\\R"=0.1+0.00385+0.46154+0.00385+0.04\\\\R"=0.60924\ K.m^2/W\)

Area = A = height * width = 1.5 m × 2.4 m = 3.6 m²

The change in temperature = ΔT = 20 °C - (-5 °C) = 25 °C

The rate of heat loss is given as:

\(\dot {Q}=A*\frac{\Delta T}{R"}= 3.6*\frac{25}{0.60924}\\ \\\dot {Q}=147.73\ W\)

The inner surface temperature (Ti) is given as:

If a multimeter reads "0.00" while performing a diode check on both sides of the diode, it indicates that the diode is a short circuit. This means that the diode has no resistance and is allowing current to flow in both directions, which is not the intended behavior of a diode.

A diode is a semiconductor device that allows current to flow in only one direction. It has two terminals, namely an anode and a cathode. The anode is the positive terminal, while the cathode is the negative terminal. When a voltage is applied across the diode in the forward direction, it conducts current, and when the voltage is applied in the reverse direction, it blocks the current flow.

A multimeter is an electronic instrument that is used to measure various electrical parameters like voltage, current, and resistance. It can also be used to check the polarity and continuity of a diode. To perform a diode check, the multimeter is set to the diode test mode, and the red probe is connected to the anode, while the black probe is connected to the cathode.

In conclusion, if the multimeter reads "0.00" while performing a diode check on both sides of the diode, it indicates that the diode is a short circuit. In this case, the diode needs to be replaced with a new one to ensure proper functioning of the circuit.

The amount of torque produced by a motor at the instant the load causes it to stall is called the "stall torque." When a motor operates at its rated voltage and frequency, it is designed to deliver a specific amount of torque to drive the load it is connected to.

Torque is the rotational force exerted by the motor to generate motion or maintain the position of the load. The motor's ability to produce torque depends on factors such as its design, construction, and power supply.

Under normal operating conditions, the motor generates torque that is sufficient to overcome the load and maintain rotation. However, when the load exceeds the motor's torque capability, the motor reaches its maximum torque output, known as the stall torque. At this point, the motor cannot produce enough torque to continue rotating, and it comes to a halt or stalls.

The stall torque is a crucial parameter in motor specifications as it provides information about the motor's ability to handle heavy loads or start-up conditions where a high torque is required. It represents the maximum torque output that the motor can generate when it is unable to overcome the load and maintain rotation.

Motor manufacturers provide stall torque ratings in motor datasheets or technical specifications. It is important to consider the stall torque when selecting a motor for applications where the load demands high starting torque or requires the motor to handle heavy loads without stalling.

Two special occasions where you should downshift are when driving on steep downhill roads and when needing additional power for overtaking or ascending steep hills.

Firstly, downshifting on steep downhill roads is important for maintaining control and preventing excessive wear on your brakes. When you downshift to a lower gear, the engine's braking effect is utilized to help maintain a safe and manageable speed without over-relying on the brake system. This technique, called engine braking, can prevent brake overheating and potential brake failure, ensuring a safer driving experience.

Secondly, downshifting is beneficial when additional power is required for overtaking another vehicle or climbing steep hills. Shifting to a lower gear increases the engine's RPM, providing more torque and power to the wheels. This improved power delivery enables smoother and safer overtaking or hill climbing, as it allows for quicker acceleration and better traction on inclines. Utilizing the appropriate gear in these situations ensures efficient power output and reduces strain on the vehicle's engine.

In summary, downshifting is particularly important during special occasions such as driving on steep downhill roads and when additional power is required for overtaking or ascending steep hills. These situations require attentive and safe driving practices, and downshifting is a key technique to ensure optimal vehicle control and performance.

Answer:

the   isentropic efficiency of turbine is 99.65%

Explanation:

Given that:

Mass flow rate of LNG  m = 20 kg/s

The pressure at the inlet \(P_1 =30 \ bar\)  = 3000 kPa

turbine temperature at the inlet \(T_1 = -160^0C\) = ( -160+273)K = 113K

The pressure at the turbine exit \(P_2 = 3 bar\) = 300 kPa

Power produced by the turbine  W = 120 kW

Density of LNG \(\rho = 423.8 \ kg/m^3\)

The formula for the workdone by an ideal turbine can be expressed by:

\(W_{ideal} = \int\limits^2_1 {V} \, dP\)

\(W_{ideal} ={V} \int\limits^2_1 \, dP\)

\(W_{ideal} ={V} [P]^2_{1}\)

\(W_{ideal} ={V} [P_1-P_2]\)

We all know that density = mass * volume i.e \(\rho= m*V\)

Then ;

\(V = \dfrac{m}{\rho}\)

replacing it into the above previous derived formula; we have:

\(W_{ideal} ={ \dfrac{m}{\rho}} [P_1-P_2]\)

\(W_{ideal} ={ \dfrac{20}{423.8}} [3000-300]\)

\(W_{ideal} ={ \dfrac{20}{423.8}} [2700]\)

\(W_{ideal} =0.04719*[2700]\)

\(W_{ideal} =127.42 kW\)

However ; the isentropic efficiency of turbine is given by the relation:

\(n_{isen} =\dfrac{W}{W_{ideal}}\)

\(n_{isen} =\dfrac{120}{120.42}\)

\(n_{isen} =0.9965\)

\(n_{isen} =\) 99.65%

Therefore, the   isentropic efficiency of turbine is 99.65%

The shafts that satisfy the condition that the twisting deformation does not distort their cross sections are called circular or circular-polar shafts.

What are circular or circular-polar shafts?

In these types of shafts, the cross-sectional shape remains constant, and the deformation is uniform throughout the length of the shaft.

Circular-polar shafts have a constant cross-sectional diameter, and the axis of the shaft is a polar axis, which means it passes through the centroid of the cross-section. This results in a uniform distribution of stress and strain, and therefore, the cross-section remains unchanged under torsional loads.

Examples of circular-polar shafts include round rods and pipes, which are widely used in various mechanical and structural applications. These shafts are relatively simple to manufacture and have good torsional strength, making them an ideal choice for many engineering applications.

liquidated damages.(a) How many more men should the contractor add so that he would complete the work on time?In the first case, we see that the contractor already has 80 men and they are working for 130 days to complete the job. So, we can use the following formula to determine the additional number of workers required to finish the work in 100 days.

b) If of the additional men, 2 are paid ₱180.00 a day, and the rest at ₱120.00 a day, would the contractor save money by employing more men and not paying the fine Let’s assume that the contractor adds 440 workers, of which 2 are paid ₱180.00 a day and the rest are paid ₱120.00 a day.

The total cost of the new workers is, therefore, ₱9600.00 + ₱4500.00 + ₱49800.00 = ₱63,900.00.The cost of liquidated damages would be calculated as follows:  $$LD = (130-100) \cdot 500 = ₱15,000.00$$.

Therefore, the contractor would save money if he employs more men and not pays the fine. The contractor’s savings would be:$$Savings = LD - Additional cost$$$$= 15000.00 - 63900.00 $$$$= -48900.00$$
