Answer:

See explanation

Explanation:

Solution:-

- The shell and tube heat exchanger are designated by the order of tube and shell passes.

- A single tube pass: The fluid enters from inlet, exchange of heat, the fluid exits.

- A multiple tube pass: The fluid enters from inlet, exchange of heat, U bend of the fluid, exchange of heat, .... ( nth order of pass ), and then exits.

- By increasing the number of passes we have increased the "retention time" of a specific volume of tube fluid; hence, providing sufficient time for the fluid to exchange heat with the shell fluid.

- By making more U-turns we are allowing greater length for the fluid flow to develop with " constriction and turns " into turbulence. This turbulence usually at the final passes allows mixing of fluid and increases the heat transfer coefficient by:

                                U ∝ v^( 0.8 )    .... ( turbulence )

- The higher the velocity of the fluids the greater the heat transfer coefficient. The increase in the heat transfer coefficient will allow less heat energy carried by either of the fluids to be wasted ; hence, reduced losses.

Thereby, increases the thermal efficiency of the heat exchanger ( higher NTU units ).

The integral is ∫[0 to R] ∫[0 to 2π] ∫[z_min to z_max] (r³ * cos²(θ)) dz dθ dr

To evaluate the triple integral of x² dV using cylindrical coordinates, we need to express the integral limits in terms of cylindrical coordinates and convert the differential volume element dV into cylindrical coordinates as well.

In cylindrical coordinates, we have:

x = r * cos(θ)

y = r * sin(θ)

z = z

Substituting the cylindrical coordinates, we have:

(r * cos(θ))² + (r * sin(θ))² ≤ R²

r²* cos²(θ) + r² * sin²(θ) ≤ R²

r² ≤ R²

The differential volume element dV in cylindrical coordinates is given by:

dV = r * dr * dθ * dz

Now, let's express the triple integral in cylindrical coordinates:

∭(x²) dV = ∭(r² * cos²(θ)) * (r * dr * dθ * dz)

The integral becomes: ∫[0 to R] ∫[0 to 2π] ∫[z_min to z_max] (r³ * cos²(θ)) dz dθ dr

Answer: hydraulic retention time,τ=28.67 hours

Explanation:

The hydraulic retention time  τ (tau),  is given as  The volume of the settling tank(V) divided by the influent flowrate(Q)

τ =V/Q

But Volume is not known  and is given as

Volume =  surface area  x depth of the tank

= 8000 ft² X 12 ft

= 96,000 ft³

Also, the influent flow rate is in mgd ( million gallons per day), we change  it to  ft³/sec so as to be in same unit with the volume in ft³

1 million gallons/day = 1.5472286365101 cubic feet/second

0.6mgd =  1.5472286365101 cubic feet/second  x 0.6

=0.93cubic feet/second

τ =V/Q

96,000 ft³/0.93 ft³/sec

τ=103,225.8 secs

changing to hours

103,225.8 /3600 =28.67 hours

The hydraulic retention time =28.67 hours

The magnitude of σ1 that will cause yielding according to the maximum-shear-stress theory is 9.94 ksi.

Yield stress for the zirconium-magnesium alloy, σY = 15.3 ksi

In-plane principal stresses are σ1 and σ2 = −0.54σ1

To find the maximum shear stress theory, the equation used is τ_max=1/2(σ1-σ2)

The maximum shear stress theory states that yielding begins when the maximum shear stress in a part equals or exceeds the shear strength of the material. It is represented as τ_max = τ_yield

Where τ_max is the maximum shear stress in a part and τ_yield is the shear strength of the material. In-plane principal stresses are σ1 and σ2 = −0.54σ1

Let us replace the value of σ2 in terms of σ1σ2 = −0.54σ1,σ1 = 1.85σ2

Substitute the values in the τ_max=1/2(σ1-σ2)

τ_max=1/2(σ1-(-0.54σ1))

τ_max=0.77σ1

Now, τ_yield= σY/2 = 7.65 ksi

Therefore, 0.77σ1 = 7.65

σ1 = 9.94 ksi

Answer:

1964

Explanation:

It was discovered in 1964 when a pair of Geiger counters were carried on board a sub-orbital rocket launched from New Mexico.

The given statement "if the contactor contacts become burned or pitted it is possible that they could develop voltage drop" is true because  when the contactor contacts become burned or pitted, it can lead to voltage drop.

When the contacts of a contactor become burned or pitted, it can lead to voltage drop. The contactor is an electrical switch used in various applications to control the flow of electricity. It consists of movable contacts that make or break the electrical circuit when energized. Over time, due to arcing and electrical currents passing through the contacts, they can become damaged and worn out.

Burned or pitted contacts have a reduced surface area for electrical conduction, which can impede the flow of current and result in voltage drop across the contactor. This can have detrimental effects on the performance of the electrical system, leading to issues such as reduced voltage at the load or increased power consumption.

The use of extra pads for outriggers in crane operations is beneficial for stability and safety. However, it is important to follow safety guidelines and not stack the pads on top of each other. These pads should be placed in a single layer to spread the load evenly and improve overall stability. Placing extra pads in violation of safety guidelines is not safe.

Outriggers have an important role to play in safety and balance when it comes to crane operations, particularly in rugged terrains and areas with uneven soil, deep excavations, and heavy loads. The outrigger pads, which are made of wood, aluminum, or high-strength plastic, serve as a base for the outriggers to provide a secure foundation for the crane's support legs to work on the ground.

Hence, when the crane lifts heavy loads, the outrigger pads help to spread the load evenly across a wider surface area, reducing ground pressure and increasing stability.

Below are the true statements about extra pads for outriggers:

1. Extra pads for outriggers may be utilized to increase stability, but they must not be stacked on top of each other.

2. Extra pads for outriggers should be used to increase the surface area of support when working on rough or delicate surfaces.

3. Extra pads for outriggers may be placed in a manner that violates the correct safety guidelines.

4. Extra pads for outriggers may be utilized to boost the crane's ability to operate on a slope.

The incorrect statement among the alternatives is: Extra pads for outriggers may be placed in a manner that violates the correct safety guidelines.

When setting up an outrigger-supported crane, it is critical to follow the manufacturer's directions for proper outrigger positioning, including ground conditions, pad positioning, and leveling. The pads should be placed in a single layer to improve the crane's overall safety and stability. Also, the pads should be used in compliance with the specified load capacity, and the crane should never be operated beyond its rated capacity.

Therefore, it is not safe to place extra pads in such a manner that it violates the safety guidelines.

Answer: the heat flux increases as the velocity boundary layer transitions to laminar to turbulent.

Explanation:

The correct statement about the relation between the velocity boundary layer and heat transfer for flow over a flat plate that is uniform in temperature is that the heat flux increases as the velocity boundary layer transitions to laminar to turbulent.

It should be noted that the heat goes in a streamline direction in a laminar flow, thereby the molecules less collide with each other. On the other hand, the direction is zig zag in a turbulent heat flux and this will bring about more collision of the molecules which leads to a rise in the heat flux.

Tensile stress in a thin wall spherical shell is given by

σ = ( p r ) /2t

This is the type of stress that involves pulling out. it is the opposite of compressive stress.

The tensile stress, σ  at the circumference of the shell is the hoop stress. The value equals that of pressure acting on the area.

Therefore:

σ * 2πr * t = p * πr^2

where

2πr = circumference of a circle

It should be noted that Weight within limits, CG out of limits

When the weight of an aircraft is within the specified limits, but the CG (center of gravity) is out of limits, it can have significant implications on the aircraft's stability and control.

The CG location plays a crucial role in determining an aircraft's stability and handling characteristics. If the CG is too far forward, the aircraft may be difficult to rotate during takeoff, and it may be prone to nose-over on landing. On the other hand, if the CG is too far aft, the aircraft may be difficult to control in pitch and may be prone to stall or spin.

If the CG is out of limits, the aircraft's stability and control may be compromised, which could lead to an unsafe situation. Pilots should always ensure that the aircraft's weight and balance are within the specified limits before takeoff.

In such a situation, the aircraft may require corrective action to bring the CG back within the limits, such as moving weight forward or aft, depending on the aircraft's design and the location of the payload.

Answer:

a) The operation of a heat pump involves the extraction of energy in the form of heat Q₁ from a cold source

b) The modifications required to convert a plant operating on an ideal Carnot cycle to a plant operating on a Rankine cycle involves

i) Complete condensation of the vapor at the condenser to saturated liquid for pumping to the boiler

ii) Heating of the pumped, pressurized water to the boiler pressure

Explanation:

a) 1 - 2. Wet vapor enters compressor where it undergoes isentropic compression to state 2 by work W₁₂  

2 - 3. The vapor enters the condenser at state 2 where it undergoes isobaric and isothermal condensation to a liquid with the evolution of heat  Q₂

3 - 4. The condensed liquid is expanded isentropically with the work done equal to W₃₋₄

4 - 1. At the state 4, with reduced pressure from the previous expansion, the liquid makes its way to the evaporator where it absorbs heat, Q₁, from the body to be cooled.

b. i) Complete condensation of the vapor at the condenser to saturated liquid for pumping to the boiler

Here the condensation process is modified from partial condensation to complete condensation at the same temperature which reduces the size of the pump required to pump the liquid water as opposed to pumping steam plus liquid

ii) Heating of the pumped, pressurized water to the boiler pressure

The pumped water at state 4 will be required to be heated to saturated water temperature equivalent to the boiler pressure, hence heat will need to be added at state.

Sketches of the schematic of a Basic Rankine cycle is attached  

Answer:

Explanation:

Given that:

diameter = 100 mm

initial temperature = 500 ° C

Conventional coefficient = 500 W/m^2 K

length  = 1 m

We obtain the following data from the tables A-1;

For the stainless steel of the rod \(\overline T = 548 \ K\)

\(\rho = 7900 \ kg/m^3\)

\(K = 19.0 \ W/mk \\ \\ C_p = 545 \ J/kg.K\)

\(\alpha = 4.40 \times 10^{-6} \ m^2/s \\ \\ B_i = \dfrac{h(\rho/4)}{K} \\ \\ =0.657\)

Here, we can't apply the lumped capacitance method, since Bi > 0.1

\(\theta_o = \dfrac{T_o-T_{\infty}}{T_i -T_\infty}} \\ \\ \theta_o = \dfrac{50-30}{500 -30}} \\ \\ \theta_o = 0.0426\\\)

\(0.0426 = c_1 \ exp (- E^2_1 F_o_)\\ \\ \\ 0.0426 = 1.1382 \ exp (-10.9287)^2 \ f_o \\ \\ = f_o = \dfrac{In(0.0374)}{0.863} \\ \\ f_o = 3.81\)

\(t_f = \dfrac{f_o r^2}{\alpha} \\ \\ t_f = \dfrac{3.81 \times (0.05)^2}{4.40 \times 10^{-6}} \\ \\ t_f= 2162.5 \\ \\ t_f = 36 mins\)

However, on a single rod, the energy extracted is:

\(\theta = pcv (T_i - T_{\infty} )(1 - \dfrac{2 \theta}{c} J_1 (\zeta) ) \\ \\ = 7900 \\times 546 \times 0.007854 \times (500 -300) (1 - \dfrac{2 \times 0.0426}{1.3643}) \\ \\ \theta = 1.54 \times 10^7 \ J\)

Hence, for centerline temperature at 50 °C;

The surface temperature is:

\(T(r_o,t) = T_{\infty} +(T_1 -T_{\infty}) \theta_o \ J_o(\zeta_1) \\ \\ = 30 + (500-30) \times 0.0426 \times 0.5386 \\ \\ \mathbf{T(r_o,t) = 41.69 ^0 \ C}\)

In order to draw the amplitude modulation, connect the power supply to the protoboard, onnect the fixed capacitor (220 microfarads) in parallel with the power supply to filter any noise and connect the fixed resistor (100 ohms) in series with the base of the NPN transistor.

A transmitting device that employs Amplitude Modulation (AM) is a necessary component for transferring information across radio waves.

The audio input is passed through an equipping capacitor C1, barring any Direct Current (DC) potential from the audio generator. Then, transistor Q1 intensively amplifies the incoming signal after its been regulated in a base bias configuration by R1 and R2 voltage dividers.
