The frequency of the AC supply is 0.036 Hz.

We know that an alternating current circuit is the kind of circuit in which we do have the resistor in addition to the to the capacitor or the inductor or both as the case may be.

Here we are told that; A 32x10^-6 F capacitor is connected to a 60V AC supply in series with a 56 ohm resistor. The current flowing in the circuit is 0.16 A.

We can tell that the impedance of the circuit can be obtained by the use of the formula;

V = IZ

V = voltage

I = current

Z = impedance

Z = V/I

Z = 60 V/0.16 A

Z = 375 ohms

Then we have;

Z = √R^2 - XC^2

375 = √(56)^2 - (1/2 * 3.142 * f *  32x10^-6)^ 2

140625 = 3136 - (1/2 * 3.142 * f *  32x10^-6)^ 2

140625 -  3136  =  (1/2 * 3.142 * f *  32x10^-6)^ 2

137489 = 1/2 * 10^-4 f

137489 * 2 * 10^-4 f = 1

f = 1/137489 * 2 * 10^-4

f = 0.036 Hz

Answer:

A) 61.628 Ib/ft^2

B) 3.271 Ibf

Explanation:

diameter of pipe = 3.28 inches

diameter of nozzle = 1.64 inches

flow rate = 26.5 gpm =  

convert the flow rate to ft^3/s

= 26.5 gpm * 0.133681 ft^3/gallons * 1 min/ 60 seconds

= 0.059 ft^3/s

next we calculate the velocity in the pipe

Q = \(\frac{\pi }{4} d^{2} _{1} V1\)

Q = 0.059

d1 = (3.28 / 12 )

hence V1 = ( 0.059 ) / (0.0747 * 0.7854 ) = 1 .01 ft/s

velocity in the Nozzle

Q = \(\frac{\pi }{4} d^{2} _{2} V2\)

Q = 0.059

d2 = ( 1.64 /12 )

hence V2 = ( 0.059 ) / ( 0.7854 * 0.0187 ) = 4.02 ft/s

A) To determine the Minimum static pressure  we apply the Bernoulli's equation

since the pipe and the Nozzle are at the same height the equation will be modified as

\(\frac{P1}{w} + \frac{V^2_{1} }{2g} = \frac{P2}{w} + \frac{v_{2} ^2}{2g}\)

where w = 62.4 Ib/ft^3

V1 = 1.01

V2 = 4.02

P1 = ?

P2 = 0

g = 9.81

hence P1 ( static pressure ) = 62.4 * 0.772 = 61.628 Ib/ft^2

B) evaluate the axial force of the Nozzle assembly on the pipe flange

The temperature of the aluminum rod at which the normal stress is equal to -10 ksi is approximately 74.92°F.

To determine the temperature at which the normal stress in the aluminum rod will be equal to -10 ksi, we can use the concept of thermal expansion and stress-strain relationship.

Given:

Gap between the composite rod and the wall: 0.02 in

Aluminum:

  Cross-sectional area (A): 2.8 in^2

  Young's modulus (E): 10.6 x 10^6 psi

  Coefficient of linear expansion (α): 12 x 10^-5 /°F

Desired normal stress: -10 ksi

First, let's calculate the change in length of the aluminum rod caused by the change in temperature:

ΔL = α * L * ΔT

Where:

ΔL is the change in length

α is the coefficient of linear expansion

L is the original length of the rod

ΔT is the change in temperature

Since the gap between the rod and the wall is given as 0.02 in, we can express the change in length as:

ΔL = Gap = 0.02 in

Now, we can calculate the change in temperature (ΔT) using the formula:

ΔT = ΔL / (α * L)

Substituting the given values:

ΔT = 0.02 in / (12 x 10^-5 /°F * L)

Next, we can calculate the change in stress (Δσ) using the formula:

Δσ = E * α * ΔT

Since we want the normal stress to be -10 ksi, we can set Δσ equal to -10 ksi and solve for the change in temperature (ΔT). Rearranging the formula:

ΔT = -10 ksi / (E * α)

Substituting the given values for E and α:

ΔT = -10 ksi / (10.6 x 10^6 psi * 12 x 10^-5 /°F)

Calculating ΔT:

ΔT = -10 / (10.6 * 12) = -0.0787 °F

To find the temperature at which the normal stress in the aluminum rod will be equal to -10 ksi, we need to add ΔT to the initial temperature of 75°F:

Temperature = 75°F + (-0.0787°F) = 74.92°F

Therefore, the temperature of the aluminum rod at which the normal stress is equal to -10 ksi is approximately 74.92°F.

Answer:

the lead of a 1/2 inch diameter drill with a 118 degree included angle is approximately 0.661 inches.

Explanation:

The lead of a drill bit is the distance that the bit advances axially for each complete revolution. The formula for lead is:

lead = (π / tan(θ)) x d

where:

- π is the mathematical constant pi (approximately 3.14159)

- θ is the included angle of the drill bit (in radians)

- d is the diameter of the drill bit

In this case, the diameter of the drill bit is given as 1/2 inch. We need to convert this to inches:

d = 1/2 inch = 0.5 inches

The included angle of the drill bit is given as 118 degrees. We need to convert this to radians:

θ = 118 degrees x (π / 180 degrees) = 2.058 radians

Now we can use the formula to calculate the lead:

lead = (π / tan(θ)) x d

= (π / tan(2.058)) x 0.5

≈ 0.661 inches

Therefore, the lead of a 1/2 inch diameter drill with a 118 degree included angle is approximately 0.661 inches.

Answer:

The distributions of solid wastes produced daily at a commercial facility are normally distributed with a mean of 10 yd3 and a standard deviation of 7 yd3. If you were to make a container size recommendation for this facility, what size would you propose? What important tradeoffs should be considered when selecting the size of the container?

It's quite perplexing to determine the perfect size of container for a facility whose waste quantity varies and is subject to changes frequently. A certain degree of burstiness is present in the distribution of solid waste generated on a daily basis in a commercial facility. However, using the available mean and standard deviation values, we can infer that a container size of 24 yd3 should be sufficient to hold the daily waste generated, considering that it's two standard deviations above the mean.

When selecting a container size, various tradeoffs must be considered. A large container is more efficient, as it would not require to be emptied as frequently, but it might be expensive and may take up more space. A smaller container may be less expensive and take up less space, but it would need to be emptied more frequently, which can result in higher transportation costs and more time spent on waste management. It is therefore essential to strike a balance between the frequency of emptying and the container size to ensure that the waste is managed effectively and efficiently.

The most nearly equivalent annual cost of each truck is approximately $14,850.

To calculate the equivalent annual cost of each truck, we need to consider the initial cost, operating and maintenance costs, salvage value, and the interest rate.

The operating and maintenance costs increase by $2,000 per year, starting from $11,500 in the first year. So, the costs for each year would be as follows:

Year 1: $11,500

Year 2: $11,500 + $2,000 = $13,500

Year 3: $13,500 + $2,000 = $15,500

Year 4: $15,500 + $2,000 = $17,500

Year 5: $17,500 + $2,000 = $19,500

Now, let's calculate the equivalent annual cost using the concept of present value. We'll use the formula for the present value of an annuity:

\(PV = C * (1 - (1 + r)^(-n)) / r,\)

where PV is the present value, C is the annual cost, r is the interest rate, and n is the number of years.

We'll calculate the present value for each year and then sum them up.

Year 1: PV1 = $40,000 + $11,500 /\((1 + 0.12)^1\)

Year 2: PV2 = $13,500 /\((1 + 0.12)^2\)

Year 3: PV3 = $15,500 /\((1 + 0.12)^3\)

Year 4: PV4 = $17,500 /\((1 + 0.12)^4\)

Year 5: PV5 = ($19,500 + $9,000) / (1 + 0.12)^5

Now, we can calculate the equivalent annual cost:

Equivalent Annual Cost = (PV1 + PV2 + PV3 + PV4 + PV5) / 5

Calculating the values and summing them up:

PV1 ≈ $31,160.71

PV2 ≈ $10,267.68

PV3 ≈ $10,853.94

PV4 ≈ $11,228.60

PV5 ≈ $12,739.96

Equivalent Annual Cost ≈ ($31,160.71 + $10,267.68 + $10,853.94 + $11,228.60 + $12,739.96) / 5

                    ≈ $14,850.18

Therefore, the most nearly equivalent annual cost of each truck is approximately $14,850.

Assuming 100% energy conversion efficiency, a 4.3 MW wind turbine operating at full capacity for one day is equivalent to approximately X = 103.2 MWh barrels of oil.

To determine the number of barrels of oil equivalent to the electrical energy generated by the wind turbine, we need to consider the energy conversion efficiency of the turbine and the energy content of a barrel of oil.

Assuming 100% energy conversion efficiency means that all the electrical energy produced by the wind turbine is accounted for. Therefore, we can directly calculate the energy generated.

Energy (in MWh) = Power (in MW) × Time (in hours)
Energy = 4.3 MW × 24 hours = 103.2 MWh

To convert this electrical energy to the energy content of oil, we need to know the energy content of a barrel of oil, which is typically measured in barrels of oil equivalent (BOE). The energy content of a BOE varies depending on the specific properties of the oil being considered.

Let's assume a hypothetical value of 1 MWh of electrical energy being equivalent to X barrels of oil. In this case, we have:

103.2 MWh = X barrels of oil
X = 103.2 MWh

Therefore, the number of barrels of oil equivalent to the electrical energy created by the wind turbine is determined by the specific conversion factor for a given energy content of oil.

PCMs with high latent heat and appropriate phase transition temperatures are chosen to ensure efficient energy storage and release. Common PCMs used in this context include paraffin wax, salt hydrates, and fatty acids.

In terms of thermal properties, the phase-change cement composite exhibits a high thermal conductivity, allowing for effective heat transfer between the PCM particles and the surrounding environment. This feature enables rapid charging and discharging of thermal energy, improving the overall performance of the storage system.

The mechanical properties of the composite are also carefully considered to ensure its durability and structural integrity. The addition of PCMs should not compromise the overall strength and stability of the cement matrix. Therefore, suitable additives and reinforcement techniques are employed to enhance the mechanical properties, such as the use of fibers or nano-materials.

The phase-change cement composite shows promise in various thermal energy storage applications, including buildings, solar thermal systems, and waste heat recovery. Its ability to store and release thermal energy efficiently can help reduce energy consumption, improve energy management, and mitigate the impact of peak energy demands.

Overall, this novel phase-change cement composite offers a viable solution for thermal energy storage, combining the benefits of cement as a construction material and the heat storage capabilities of phase-change materials.
