A compressible fluid flows through a compressor that increases the density from 1 kg/m3 to 5 kg/m3. The cross-sectional area of the inlet pipe is 3 m2 and that of the discharge pipe is 1 m2. The relation between the discharge volume flow rate and the inlet volume flow rate is
Answers
Answer:
The relation between the discharge volume flow rate and the inlet volume flow rate is \(\frac{1}{5}\).
Explanation:
No matter if fluid is compressible or not, mass throughout compressor, a device that works at steady state, must be conserved according to Principle of Mass Conservation:
\(\dot m_{in}-\dot m_{out} = 0\) (Eq. 1)
Where \(\dot m_{in}\) and \(\dot m_{out}\) are mass flows at inlet and outlet, measured in kilograms per second.
After applying Dimensional analysis, we expand the equation above as follows:
\(\rho_{in}\cdot \dot V_{in} - \rho_{out}\cdot \dot V_{out} = 0\) (Eq. 2)
Where:
\(\rho_{in}\), \(\rho_{out}\) - Fluid densities at inlet and outlet, measured in kilograms per cubic meter.
\(\dot V_{in}\), \(\dot V_{out}\) - Volume flow rates at inlet and outlet, measured in cubic meters per second.
After some algebraic handling, we find the following relationship:
\(\rho_{out}\cdot \dot V_{out} = \rho_{in}\cdot \dot V_{in}\)
\(\frac{\dot V_{out}}{V_{in}} = \frac{\rho_{in}}{\rho_{out}}\) (Eq. 3)
If we know that \(\rho_{in} = 1\,\frac{kg}{m^{3}}\) and \(\rho_{out} = 5\,\frac{kg}{m^{3}}\), then the relation between the discharge volume flow rate and the inlet volume flow rate is:
\(\frac{\dot V_{out}}{\dot V_{in}} = \frac{1\,\frac{kg}{m^{2}} }{5\,\frac{kg}{m^{3}} }\)
\(\frac{\dot V_{out}}{\dot V_{in}} = \frac{1}{5}\)
The relation between the discharge volume flow rate and the inlet volume flow rate is \(\frac{1}{5}\).

: The interior wall of a furnace is maintained at a temperature of 900 0C. The wall is 60 cm thick, 1 m wide, 1.5 m broad of material whose thermal conductivity is 0.4 W/m K. The temperature of the outside surface of the wall is 150 0C. Determine the heat through the wall. Also determine thermal resistance to heat flow.
Answers
Answer:
Heat is lost at the rate of 750 J/s or W
The thermal resistance is 1 K/W
Explanation:
interior temperature \(T_{2}\) = 900 °C
wall thickness t = 60 cm = 0.6 m
width = 1 m
breadth = 1.5 m
thermal conductivity k = 0.4 W/m-K
outside temperature \(T_{1}\) = 150 °C
heat through the wall = ?
The area of the wall A = w x b = 1 x 1.5 = 1.5 m^2
Temperature difference \(dt\) = \(T_{2}\) - \(T_{1}\) = 900 - 150 = 750 °C
note that \(dt\) is also equal to 750 K since to convert from °C to K we'll have to add 273 to both temperature, which will still cancel out when we subtract the two temperatures.
To get the heat that escapes through the wall, we use the equation
Q = Ak\(\frac{dt}{t}\)
substituting values, we have
Q = 1.5 x 0.4 x \(\frac{750}{0.6}\) = 750 J/s or W
Thermal resistance \(R_{t}\) = \(\frac{dt}{Q}\)
\(R_{t}\) = 750/750 = 1 K/W
One pound of air in a cylinder-piston arrangement undergoes an adiabatic expansion from 200 psia to 50 psia. The initial volume is 4 ft3/lbm. The process is such that PV1.4 is constant. Find the work done and the change in internal energy and temperature of the gas.
Answers
When air undergoes adiabatic expansion, the process is governed by the equation PV^γ = constant, where γ is the ratio of specific heats. In this case, the value of γ for air is 1.4. We are given that one pound of air undergoes an adiabatic expansion from 200 psia to 50 psia, with an initial volume of 4 ft3/lbm and PV^1.4 = constant.
Let's calculate the final volume of the air using the initial and final pressures and the initial volume. Using the formula P1V1^γ = P2V2^γ and substituting the given values, we have: 200(4)^1.4 = 50(V2)^1.4V2 = (200(4)^1.4 / 50)^(1/1.4)V2 = 11.14 ft^3/lbmThe work done by the air is given by the equation W = ∆E + Q, where ∆E is the change in internal energy and Q is the heat added to or removed from the system. Since the process is adiabatic (Q = 0), the work done is equal to the change in internal energy. Let's calculate the work done:W = ∆E = C_v (T2 - T1)where C_v is the specific heat at constant volume, and T1 and T2 are the initial and final temperatures, respectively. The specific heat at constant volume for air is 0.1715 Btu/lbm·R. Let's calculate the final temperature of the air using the initial and final pressures and volumes and the equation P1V1^γ/T1 = P2V2^γ/T2.200(4)^1.4/T1 = 50(11.14)^1.4/T2T2 = T1 * (P2V2^γ / P1V1^γ)T2 = 1183.3 RLet's substitute the values into the equation for work done to get:W = C_v (T2 - T1)W = 0.1715 Btu/lbm·R (1183.3 R - 527.7 R)W = 0.1715 Btu/lbm·R (655.6 R)W = 112.3 Btu/lbmThe change in internal energy is also 112.3 Btu/lbm, since Q = 0. The change in temperature is T2 - T1 = 1183.3 R - 527.7 R = 655.6 R.Answer: The work done by the air is 112.3 Btu/lbm, and the change in internal energy and temperature of the gas are also 112.3 Btu/lbm and 655.6 R, respectively.

Answers
Therefore, roughly 12 drain holes with a diameter of 0.4 inches would be required to prevent the sink from overflowing with water.
Two gal of water per minute enter the sink. The water will eventually go through the overflow drain holes if the drain is closed as opposed to over the edge of the sink. number of 0.4-in.

A hollow cast iron 5m long column with both ends fixed is required for support a load of 1000KN if the external diameter of the column is 250mm find its thickness take working stress as 80mpa and rankings constant as 1/1600
Answers
The required thickness of the cast iron column is approximately 16.8mm. we can use the formula for the buckling stress of a column:σ_critical = π^2 * E / (KL/r)^2
What is buckling Stress?
The abrupt change in shape (deformation) of a structural component under load, such as the bowing of a column under compression or the wrinkling of a plate under shear, is referred to as buckling in structural engineering.
To find the required thickness of the cast iron column, we can use the formula for the buckling stress of a column:
σ_critical = π^2 * E / (KL/r)^2
where σ_critical is the critical buckling stress, E is the modulus of elasticity of cast iron, K is the Rankine's constant (1/1600 for a fixed-fixed column), L = length of the column, and r = radius of the column.
The external diameter of the column is 250mm, so the radius is r = 250/2 = 125mm.
The modulus of elasticity for cast iron is around 200,000 N/mm^2.
We can then calculate the critical buckling stress:
σ_critical = π^2 * 200,000 / (1/1600 * 5000/125)^2
σ_critical = 80 N/mm^2
Since the working stress of the column is 80 N/mm^2, which is equal to the critical buckling stress, we can calculate the required thickness t using the formula for stress in a column:
σ = P / (π * r^2 / 4)
where P is the load on the column, and π * r^2 / 4 is the cross-sectional area of the column.
Given that the load on the column is 1000 KN, we can calculate the required thickness:
t = P * 4 / (π * r^2 * σ)
t = (1000 * 1000) * 4 / (π * 125^2 * 80)
t = 16.8 mm

What does a Voltage Controlled Amplifier do?
Answers
A Voltage Controlled Amplifier (VCA) is an electronic device
This device can amplify an input signal with a gain that is proportional to a control voltage applied to it. In other words, the gain of the amplifier is determined by the voltage level of a separate control input.
The basic function of a VCA is to vary the level of audio or signal in response to a control voltage, which makes it a useful component in various applications such as audio processing, modulation, and control systems. In audio applications, a VCA can be used to control the dynamic range of a signal, allowing the level of the signal to be adjusted based on the level of another signal, such as a control signal or an envelope signal.
For example, a VCA can be used in a compressor, where the gain of the VCA is controlled by the input signal level, and the output is reduced when the input signal exceeds a certain threshold. Similarly, a VCA can be used in an envelope follower, where the gain is controlled by the envelope of the input signal, allowing the level of a signal to be controlled based on its dynamic characteristics.
Overall, the VCA is a versatile electronic component that allows signals to be processed and controlled in a flexible and precise manner, making it a useful tool in various applications.

Two blocks are joined by an inextensible cable as shown, if the system is released from rest, determine the velocity of block A after it has moved 4 m. Assume that the coefficient of friction between block A and the plane equal to 0.3 and the pulley is weightless and frictionless
Answers
To determine the velocity of block A after it has moved 4 m, we can use the principles of Newton's laws of motion and energy conservation. Here are the moves toward tackle the issue:
1. First, draw a free-body diagram for each block. Block A experiences weight (mg) downward, tension (T) upward, and friction (f) opposing its motion. Block B experiences weight (2mg) downward and tension (T) upward.
2. Apply Newton's second law of motion to both blocks. For Block A, we have the equation:
T - f = ma (Equation 1)
For Block B, we have:
2mg - T = 2ma (Equation 2)
3. The erosion power can be determined as:
f = μN
N = mg (normal force)
Therefore, f = μmg, where μ is the coefficient of friction.
4. Use the constraint equation due to the inextensible cable:
s = rθ
where s is the distance traveled by block A, r is the radius of the pulley (unknown), and θ is the angle in radians subtended by the arc on the pulley.
5. Apply conservation of energy:
The change in potential energy is equal to the change in kinetic energy for block A.
mgh = (1/2)mv^2
Solving for v, we get:
v = √(2gh)
6. Use the given information that block A has moved 4 m to determine the angle θ and the radius r using the constraint equation.
7. Substitute the values of μ, m, g, and h into the equation for v to calculate the velocity of block A after it has moved 4 m.
By following these steps, you can find the velocity of block A after it has moved 4 m. Remember to double-check your calculations and units to ensure accurate results.

explain how to achieve proper drive pinion gear bearing preload
Answers
Answer: The correct way to achieve proper drive pinion gear bearing preload is to torque the pinion nut to the manufacturer’s specifications and then check for preload.
Explanation: Typical starting points for torque specifications are 55 lb-ft for 3/8-inch bolts/nuts, 75 lb-in for 7/16-inch bolt/nuts, and 125 lb-in for 1/2-inch nuts/bolts. Once the nut is properly torqued, check for preload by tapping the end of the pinion gear with a punch to ensure the races are fully seated, shake it to evaluate for excessive play.
Pinion bearings are bearings that support the weight of the drive shaft and transfer power from the differential to the wheels. Preload is the tension that is put on a bearing. In the case of pinion bearings, preload takes place in the form of a collapsible spacer that stays between the bearings. The required amount of tension is obtained by adjusting the space manually.
Other ways to achieve proper drive pinion gear bearing preload include using a crush sleeve or shims. Crush sleeves are used in place of spacers and are designed to be crushed when the pinion nut is tightened. This crushes the sleeve and creates tension on the bearings. Shims can also be used to adjust the space between bearings.
Common problems with drive pinion gear bearing preload include over-tightening or under-tightening of the pinion nut, which can lead to damage or failure of the bearings. It is important to follow manufacturer specifications when torquing the pinion nut and checking for preload.
Hope this helps, and have a great day!
shoes with thic ____________ protect feet from protruding nails and othjer charp ojects\
Answers
The term that is missing from the statement is soles. Shoes with thick soles protect feet from protruding nails and other sharp objects. The sole of a shoe is the bottom part of the shoe that comes into contact with the ground. In other words, it's the layer that lies between your foot and the shoe's upper part.
Sole can be made from a variety of materials, including rubber, leather, or a combination of the two. The sole of a shoe must be well-constructed to provide adequate protection for the feet. These types of shoes are commonly referred to as safety shoes or work boots. They are designed to provide extra protection for the feet in hazardous environments, such as construction sites or industrial settings. The thick soles act as a barrier between the feet and the ground, reducing the risk of injury from sharp objects or punctures. Additionally, safety shoes often feature reinforced toe caps, which provide further protection for the toes from heavy objects or compression.
Therefore, shoes with thick soles provide greater comfort, protection, and cushioning to the feet. Thick-soled shoes protect the feet from sharp objects that may be on the ground while walking.

A sinusoidal voltage source has a peak voltage of 12 V and a frequency of 50 Hz. What is the voltage at 10 ms?
Answers
Answer:
0
Explanation:
Given that:
The peak of the voltage \(V_{peak}\) = 12 V
The frequency f = 50 Hz
At the time t = 10 ms
\(V = V_p \ sin \ \omega t\)
where;
\(\omega = 2 \pi f\)
\(V = 1 2\ V \times sin \ ( 2 \pi \times 50 \times 10 \ )\)
V = 12V sin (180)
V = 12 V × 0
V = 0
