Answer:

a) Mt = 0.0023229

b) = U1 = 214.07

c) = V₁  = 0.861 m³/kg

d) = Vr1 = 621.2

Explanation:

Given that

R = 0.287 KJ/kg.K, T1 = 300 K , P1 = 100 kPa , V1 = 500 cm³, r = 10 , Q = 60 kW , Speed N = 5600 RPM, Number of cylinders K = 4

specific heat at constant volume Cv = 0.7174 kJ/kg.K

Specific heat at constant pressure is 1.0045 Kj/kg.K

a)  To determine the total mass (kg) of air in the engine.

we say

P1V1 = mRT1

we the figures substitute

(100 x 10³) ( 500 x  10⁻⁶) = m ( 0.287 x  10³) ( 300 )

50 = m x 86100

m = 0.00005 / 86100 = 0.0005807 ( mass of one cylinder)

Total mass of 4 cylinder

Mt = m x k

Mt = 0.0005807 x 4

Mt = 0.0023229

b) To determine the specific internal energy (kJ/kg) at state 1

i.e at T1 = 300

we obtain the value of specific internal energy U1 at 300 K ( state 1) from the table ideal gas properties of air.

U1 = 214.07

c) To determine the specific volume (m³/kg) at state 1.

we say

V₁ = V1/m

V₁ = (500 x  10⁻⁶) / 0.0005807

V₁  = 0.861 m³/kg

d) To determine the relative specific volume at state 1.

To obtain the value of relative specific volume at 300 K ( i.e state 1) from the table ideal gas properties of air.

At T1 = 300 k

The fraction of light that will be transmitted through a 32 mm thickness of the transparent material is approximately 0.59049 or 59.049%.

To determine the fraction of light that will be transmitted through a 32 mm thickness of the transparent material, we need to use the information provided.

Let's assume that the fraction of nonreflected radiation transmitted through a 10 mm thickness is 0.90. This means that 90% of the incident light is transmitted through the 10 mm thickness.

Now, we need to find the fraction of light transmitted through the 32 mm thickness. To do this, we can assume that the fraction of transmitted light remains constant throughout the material.

Since 90% of the light is transmitted through 10 mm, we can say that 90% of the transmitted light will be transmitted through the next 10 mm as well.

This means that 90% of 90% (or 0.90) will be transmitted through the second 10 mm, which is 0.90 ˣ 0.90 = 0.81.

Similarly, 90% of 0.81 will be transmitted through the next 10 mm, which is 0.90 ˣ 0.81 = 0.729.

Continuing this pattern, 90% of 0.729 will be transmitted through the next 10 mm, which is 0.90 ˣ 0.729 = 0.6561.

Finally, 90% of 0.6561 will be transmitted through the last 2 mm, which is 0.90 ˣ 0.6561 = 0.59049.

Since their blades are bent, wind turbines provide lift. Low air pressure is produced by the side of the blade-shaped aerofoil that has the largest curve, while high air pressure is produced by the side that is beneath it.

Due to the form of wind turbine blades, air molecules flowing across the downwind side of the blade move more quickly than those moving across the upwind side. An airfoil is a form that resembles a crooked teardrop.

Turbines can be made with a vertical or a horizontal axis. Their blades might be straight, curved, or rounded. An energy-producing turbine with a horizontal axis and three blades is most effective at producing power.

Most blades are constructed of epoxy or polyester reinforced with fibreglass. As reinforcement materials, we may alternatively utilise carbon fiber or aramid (Kevlar). These days, research is being done into the potential applications of wood compounds like wood-epoxy or wood-fiber-epoxy.

Improperly repaired brake systems can cause accidents, injuries, and even death. The potential consequences include loss of control, decreased stopping power, and compromised vehicle safety, which can result in collisions, personal harm, or fatalities.

When brake systems are not repaired properly, several issues can arise that jeopardize vehicle safety and increase the risk of accidents, injuries, and fatalities. One significant consequence is the loss of control over the vehicle. Faulty repairs can lead to a compromised braking ability, resulting in decreased stopping power and longer braking distances. This can make it difficult to avoid collisions, especially in emergency situations. Additionally, improperly repaired brake systems may exhibit unpredictable behavior, such as sudden brake failure or uneven braking, which can further contribute to accidents. Inadequate repairs can also lead to injuries. Malfunctioning brakes can cause sudden and unexpected stops or skidding, potentially resulting in collisions with other vehicles, pedestrians, or objects. Occupants of the vehicle may be thrown forward, causing them to collide with the interior components or be ejected from the vehicle in severe cases. The lack of reliable braking can also increase the severity of accidents, making injuries more severe. Tragically, improper repairs to brake systems can even lead to fatalities. The compromised braking ability and loss of control over the vehicle can result in high-speed collisions or accidents in hazardous conditions, significantly increasing the likelihood of fatal outcomes. Pedestrians and occupants of other vehicles are also at risk due to the decreased ability of the driver to safely operate the vehicle. Given the critical role that brakes play in vehicle safety, it is crucial to ensure that brake systems are properly repaired and maintained to prevent accidents, injuries, and potential loss of life.

The final temperature of air when expanded isentropically from 1425 kPa and 477°C to 100 kPa in a piston-cylinder device using the average specific heats from the ideal gas property tables is 315.5 K.

To determine the final temperature of air when expanded isentropically from 1425 kPa and 477°C to 100 kPa in a piston-cylinder device, we need to use the ideal gas law and the equation for isentropic expansion.
Firstly, we can use the ideal gas law to calculate the initial specific volume of air:
V1 = R*T1/P1
where V1 is the specific volume, R is the specific gas constant, T1 is the initial temperature (477°C = 750 K), and P1 is the initial pressure (1425 kPa).
V1 = 0.1989 m^3/kg
Next, we can use the equation for isentropic expansion to calculate the final specific volume of air:
V2 = V1*(P1/P2)^(1/gamma)
where V2 is the final specific volume, P2 is the final pressure (100 kPa), and gamma is the ratio of specific heats (1.4 for air).
V2 = 1.0265 m^3/kg
Finally, we can use the ideal gas law again to calculate the final temperature:
T2 = P2*V2/R
T2 = 315.5 K

The variation of temperature in the wall is T(x)= (q_0x) /(kL) + T_0. The heat flux q_n is -28.1 W/m^2 and the temperature of the left surface of the wall is T_0 = 300 degree C.

B. To obtain the variation of temperature in the wall, we need to use the heat conduction equation, which states that the rate of heat flow through a solid is proportional to the temperature gradient.

The equation is given by q_x = -kdT/dx. Since we know the heat flux q_0 at the left surface, we can integrate this equation from x = 0 to x = L to obtain the temperature distribution T(x) in terms of q_0 and the thermal conductivity k.

On the right surface, we can use the equation for heat transfer by convection and radiation, which is given by

q_n = h(T_6 - T_surrounding) + esigma(T_6^4 - T_surrounding^4)

where h is the convection heat transfer coefficient, e is the emissivity, sigma is the Stefan-Boltzmann constant, T_6 is the surface temperature and T_surrounding is the surrounding temperature.

The distance between C and E accounting for the compression of the spring and deformation of the bolts is 10.421 inches when the coupling rod is subjected to a force of 5 kip.

A mechanical system's coupling rod, also known as a connecting rod, connects two rotating parts, like an engine's crankshafts. It synchronizes the work of each rotating component by transferring power and motion from one to the other.

We can use the principle of superposition to calculate the individual contributions of the spring and bolts, and then add them together to obtain the total displacement of point E.

First, we can consider the effect of the spring. The displacement of point E due to the spring is given by:

                            ΔE_spring = F/k

where F is the force applied to the coupling rod and k is the spring stiffness. Substituting the given values, we have:

                ΔE_spring = 5 kip / 12 kip/in

                             = 0.417 in

Next, we can consider the effect of the bolts. Each bolt will undergo a change in length due to the force applied to the coupling rod. Assuming that the deformation of each bolt is proportional to its length, we can use the following equation to calculate the displacement of point E due to the bolts:

                   ΔE_bolts = (ΔL_AB + ΔL_BC + ΔL_CE) / 3

where ΔL_AB, ΔL_BC, and ΔL_CE are the changes in length of bolts AB, BC, and CE, respectively.

To calculate the changes in length of the bolts, we can use the following formula:

                         ΔL = F L / (AE E)

where L is the length of the bolt, AE is the cross-sectional area of the bolt, and E is the modulus of elasticity of the bolt material. For A-36 steel, the modulus of elasticity is 29,000 ksi.

Using this formula, we can calculate the changes in length of each bolt as follows:

ΔL_AB = (5 kip) (4 in) / ((0.25 in)² π/4 (29,000 ksi))

                           = 0.0025 in

ΔL_BC = (5 kip) (6 in) / ((0.25 in)² π/4 (29,000 ksi))

                             = 0.0037 in

ΔL_CE = (5 kip) (10 in) / ((0.25 in)² π/4 (29,000 ksi))

                               = 0.0061 in

Substituting these values into the equation for ΔE_bolts, we have:

ΔE_bolts = (0.0025 in + 0.0037 in + 0.0061 in) / 3

                           = 0.0041 in

Finally, we can add the displacements due to the spring and bolts to obtain the total displacement of point E:

ΔE_total = ΔE_spring + ΔE_bolts

                              = 0.417 in + 0.0041 in

                                       = 0.421 in

Therefore, the distance between C and E accounting for the compression of the spring and the deformation of the bolts is:

d = 10 in + ΔE_total = 10 in + 0.421 in

                          = 10.421 in

Therefore, the distance between C and E is 10.421 inches when the coupling rod is subjected to a force of 5 kip, accounting for the compression of the spring and the deformation of the bolts.

**To maintain a constant pressure in the evaporator when the system is running, an expansion valve (axv) increases refrigerant flow when the evaporator pressure drops.**

The expansion valve is a crucial component in a refrigeration system that regulates the flow of refrigerant into the evaporator. Its primary function is to reduce the pressure and temperature of the refrigerant as it enters the evaporator.

When the evaporator pressure drops, it indicates that the cooling load has increased, and more refrigerant is required to maintain the desired cooling effect. In response, the expansion valve adjusts its opening, allowing a greater flow of refrigerant into the evaporator. This increased flow helps to maintain a constant pressure within the evaporator and ensures efficient heat transfer between the refrigerant and the surrounding air or fluid.

By modulating the refrigerant flow in accordance with the evaporator pressure, the expansion valve plays a crucial role in maintaining the proper operation and performance of the refrigeration system.

To calculate delay, we need the volume of traffic and the capacity of each movement. The level of service depends on the delay experienced by the vehicles, which in turn is influenced by the traffic volumes and capacity. The critical v/c ratio indicates the desired level of congestion.Once we have the necessary information, we can apply traffic engineering methodologies such as the Highway Capacity Manual (HCM) or other appropriate models to calculate the delay and level of service for the specified movements at the intersection.

The probability that a rivet is defective is 0.0202 and  the smallest value of p that ensures that only 119 of all seams need reworking is approximately 0.0018

(a) If 1696 of all seams need reworking, we can use the complement rule to find the probability that a rivet is defective. The complement rule states that the probability of an event happening is equal to 1 minus the probability of the event not happening. So, if the probability that all 20 rivets are not defective (i.e., the seam is not defective) is 0.8496, then the probability that at least one rivet is defective is:

P(defective rivet) = 1 - P(no defective rivet)

P(defective rivet) = \(1 - 0.8496^{(1/20)\)

P(defective rivet) = 0.0202

Therefore, the probability that a rivet is defective is 0.0202, or approximately 0.0202.

(b) Let p be the probability of a defective rivet. We can use the binomial distribution to find the probability that 119 or fewer of all seams need reworking. The binomial distribution models the number of successes in a fixed number of independent trials, where each trial has the same probability of success.

The number of defective rivets in a seam follows a binomial distribution with n = 20 and p = the probability of a defective rivet. The probability that k seams need reworking is:

P(k seams need reworking) =\(C(1696, k) * p^k * (1 - p)^{(1696 - k)\)

We want to find the value of p such that P(k ≤ 119) = Σ P(k seams need reworking) is at least 0.5. This is equivalent to finding the smallest value of p such that:

\(\sum C(1696, k) * p^k * (1 - p)^{(1696 - k)} \geq 0.5\), where the sum is taken from k = 0 to 119.

This equation cannot be solved analytically, so we must use numerical methods to find p. One way to do this is to use a bisection algorithm, which repeatedly narrows down the possible range of p until we find the smallest value of p that satisfies the equation.

Using this method, we can find that the smallest value of p that ensures that only 119 of all seams need reworking is approximately 0.0018, or 0.18%.
