The work needed for the compression of an ideal gas in a single reversible and adiabatic compressor can be expressed in terms of the mass flow rate, initial pressure (P1), final pressure (P2), and initial temperature (T1).

a. When compressing an ideal gas in a single reversible and adiabatic compressor, the work required can be calculated using the equation: W = (m_dot * R * T1) * ln(P2/P1), where W is the work, m_dot is the mass flow rate, R is the gas constant, T1 is the initial temperature, and ln represents the natural logarithm. This expression takes into account the change in pressure and temperature during the compression process.

b. In a two-stage compression process, the work needed can be minimized by selecting an intermediate pressure (P*) between P1 and P2. The value of P* should be determined such that the compression process is done with minimum work. By optimizing the pressure ratio between the stages, the work required for each compression can be reduced. To calculate the specific value of P*, detailed calculations involving thermodynamic relationships and optimization techniques are required.

In summary, the work needed for compressing an ideal gas depends on factors such as the mass flow rate, initial and final pressures, and initial temperature. In a two-stage compression process, selecting the intermediate pressure (P*) carefully can help minimize the work required. Precise calculations and analysis are necessary to determine the specific value of P*.

Answer: the shear strength at a depth of 12 ft is 1034.9015 lb/ft²

Explanation:

Given that;

Weight of soil r = 118 lb/ft³

stress parameter C = 250 lb/ft²

φ total = 29°

depth Z = 12 ft

The shear strength on a horizontal plane at a depth of 12ft

ζ = C + δtanφ

where δ = normal stress

normal stress δ = r × z = 118 × 12 = 1416

so

ζ = C + δtanφ

ζ = 250 + 1416(tan29°)

ζ = 250 + 1416(tan29°)

ζ = 250 + 784.9016

ζ = 1034.9015 lb/ft²

Therefore the shear strength at a depth of 12 ft is 1034.9015 lb/ft²

In summary, the XYZ Company will require:

(a) 705 processing and assembly operations,

(b) 710 workers (direct labor only), and

(c) 25,738 m2 of total floor space for the new plant.

To calculate the required processing and assembly operations, workers, and total floor space for the new factory, we can break down the problem into smaller parts and analyze each element.

(a) Processing and assembly operations:

Number of components made in the factory: 250 components * 35% = 87.5 (round up to 88 components)

Processing operations for components: 88 components * 8 processing operations = 704 processing operations

Assembly operations for final product: 1 assembly operation (as each product is assembled in one workstation)

Total operations = 704 processing operations + 1 assembly operation = 705 operations

(b) Number of workers (direct labor only):

Processing workers: 704 processing operations / 1 (one worker per work cell) = 704 workers

Assembly workers: 13 models * 1000 units/model = 13,000 units/year

Assembly time per unit: 48 min/unit = 0.8 hr/unit

Assembly time for all products: 13,000 units * 0.8 hr/unit = 10,400 hr

Assembly workers required: 10,400 hr / 2,000 hr/shift = 5.2 (round up to 6 workers)

Total workers = 704 processing workers + 6 assembly workers = 710 workers

(c) Total floor space required:

Processing floor space: 704 work cells * 25 m2/cell = 17,600 m2

Assembly floor space: 6 workstations * 25 m2/station = 150 m2

Total production area: 17,600 m2 + 150 m2 = 17,750 m2

Additional allowance (45%): 17,750 m2 * 45% = 7,987.5 m2

Total floor space = 17,750 m2 + 7,987.5 m2 = 25,737.5 m2 (round to 25,738 m2)

In summary, the XYZ Company will require:

(a) 705 processing and assembly operations,

(b) 710 workers (direct labor only), and

(c) 25,738 m2 of total floor space for the new plant.

The experimental probability of Brandy rolling a strike in the first frame of the next game is 1/5.

Given that Brandy rolls a strike in 2 out of 10 frames in a game, we can calculate the experimental probability of her rolling a strike in the first frame of the next game. Since there are 10 frames in a game, the probability of Brandy rolling a strike in any given frame is 2/10 or 1/5. Therefore, the experimental probability of her rolling a strike in the first frame of the next game is also 1/5. This is based on the assumption that her performance in each frame is independent of the others, and the probability remains constant from frame to frame.

When conducting a study with physical evidence, the researcher needs to select an appropriate physical evidence measure that can reliably and accurately capture the behavior of interest. This measure can be a direct observation, audio recording, video recording, or any other type of physical evidence that can be collected and analyzed.

Once the researcher has identified the physical evidence measure, they will then systematically record the physical evidence by implementing a data collection plan. This plan should include specific procedures for collecting, storing, and analyzing the physical evidence to ensure that the data collected is accurate and reliable.

After collecting the physical evidence, the researcher will then compare the two variables of the hypothesis using quantitative data analysis. This involves using statistical methods to analyze the data collected and test the hypothesis, such as computing descriptive statistics, calculating correlations, and conducting inferential tests.

In summary, to conduct a study with physical evidence, the researcher needs to carefully select an appropriate physical evidence measure, systematically record the physical evidence, and use quantitative data analysis to test the hypothesis.

Answer:

The velocity at section is approximately 42.2 m/s

Explanation:

For the water flowing through the pipe, we have;

The pressure at section (1), P₁ = 300 kPa

The pressure at section (2), P₂ = 100 kPa

The diameter at section (1), D₁ = 0.1 m

The height of section (1) above section (2), D₂ = 50 m

The velocity at section (1), v₁ = 20 m/s

Let 'v₂' represent the velocity at section (2)

According to Bernoulli's equation, we have;

\(z_1 + \dfrac{P_1}{\rho \cdot g} + \dfrac{v^2_1}{2 \cdot g} = z_2 + \dfrac{P_2}{\rho \cdot g} + \dfrac{v^2_2}{2 \cdot g}\)

Where;

ρ = The density of water = 997 kg/m³

g = The acceleration due to gravity = 9.8 m/s²

z₁ = 50 m

z₂ = The reference = 0 m

By plugging in the values, we have;

\(50 \, m + \dfrac{300 \ kPa}{997 \, kg/m^3 \times 9.8 \, m/s^2} + \dfrac{(20 \, m/s)^2}{2 \times 9.8 \, m/s^2} = \dfrac{100 \ kPa}{997 \, kg/m^3 \times 9.8 \, m/s^2} + \dfrac{v_2^2}{2 \times 9.8 \, m/s^2}\)50 m + 30.704358 m + 20.4081633 m = 10.234786 m + \(\dfrac{v_2^2}{2 \times 9.8 \, m/s^2}\)

50 m + 30.704358 m + 20.4081633 m - 10.234786 m = \(\dfrac{v_2^2}{2 \times 9.8 \, m/s^2}\)

90.8777353 m = \(\dfrac{v_2^2}{2 \times 9.8 \, m/s^2}\)

v₂² = 2 × 9.8 m/s² × 90.8777353 m

v₂² = 1,781.20361 m²/s²

v₂ = √(1,781.20361 m²/s²) ≈ 42.204308 m/s

The velocity at section (2), v₂ ≈ 42.2 m/s

Answer:

mass flow rate = 0.0534 kg/sec

velocity at exit = 29.34 m/sec

Explanation:

From the information given:

Inlet:

Temperature \(T_1 = -16^0\ C\)

Quality \(x_1 = 0.2\)

Outlet:

Temperature \(T_2 = -16^0 C\)

Quality  \(x_2 = 1\)

The following data were obtained at saturation properties of R134a at the temperature of -16° C

\(v_f= 0.7428 \times 10^{-3} \ m^3/kg \\ \\ v_g = 0.1247 \ m^3 /kg\)

\(v_1 = v_f + x_1 ( vg - ( v_f)) \\ \\ v_1 = 0.7428 \times 10^{-3} + 0.2 (0.1247 -(0.7428 \times 10^{-3})) \\ \\ v_1 = 0.0255 \ m^3/kg \\ \\ \\ v_2 = v_g = 0.1247 \ m^3/kg\)

\(m = \rho_1A_1v_1 = \rho_2A_2v_2 \\ \\ m = \dfrac{1}{0.0255} \times \dfrac{\pi}{4}\times (1.7 \times 10^{-2})^2\times 6 \\ \\ \mathbf{m = 0.0534 \ kg/sec}\)

\(\rho_1A_1v_1 = \rho_2A_2v_2 \\ \\ A_1 =A_2 \\ \\ \rho_1v_1 = \rho_2v_2 \\ \\ \implies \dfrac{1}{0.0255} \times6 = \dfrac{1}{0.1247}\times (v_2)\\ \\ \\\mathbf{\\ v_2 = 29.34 \ m/sec}\)

Torque can be defined as a measure of the amount of force which causes a physical object to rotate about an axis. This ultimately implies that, torque is a force which tends to cause the rotation of a physical object about an axis.

In Mechanics, torque is also referred to as a twisting force, moment of force, moment or rotational force. Also, it is generally considered as the rotational equivalent of a linear force.
