The heat exchanger's estimated bare module price is $199,101.

The pricing of a bare module includes all necessary hardware and installation labour within a 3-meter radius. Investment = above plus royalties plus real estate plus supplies + legal + working capital plus construction-related interest Working capital is equal to 10%+ of invested fixed capital. This could differ greatly.

Bare module cost = (Cost of tubes + Cost of shell + Cost of bundle) x (Cost factor)

Tube length = \(160 / (2 x 1.3) = 61.54 m\)

Cost of tubes = \(61.54 x $50 = $3,077\)

Shell length = \(1.25 x 61.54 = 76.92 m\)

Cost of shell = \(1.5 x 76.92 x $500 = $57,690\)

Number of tubes = \(61.54 x 10 = 615\)

Assuming a cost per tube of $10, we get:

Cost of bundle =\(615 x $10 = $6,150\)

Bare module cost = \(($3,077 + $57,690 + $6,150) x 3 = $199,101\)

Answer:

Explanation:

The height of the wall = 15 ft

For the 2 x 4 in. studs:

The minimum dead load for a 2 x 4 in. studs (from table 1-3) = 4 psf = 4 lb/ft²

Therefore for a 15 ft tall wall, the dead load for a 2 x 4 in. studs = 15 ft × 4 lb/ft² = 60 lb/ft

For the 4 in. clay brick:

The minimum dead load for a 4 in. clay brick (from table 1-3) = 39 psf = 39 lb/ft²

Therefore for a 15 ft tall wall, the dead load for a 4 in. clay brick = 15 ft × 39 lb/ft² = 585 lb/ft

Therefore the average load = load for the 4 in. clay brick + load for the 2 x 4 in. studs = 585 lb/ft + 60 lb/ft = 645 lb/ft

Answer:

a) \(h_c = 0.1599 W/m^2-K\)

b) \(H_{loss} = 5.02 W\)

c) \(T_s = 302 K\)

d) \(\dot{Q} = 25.125 W\)

Explanation:

Non horizontal pipe diameter, d = 25 cm = 0.25 m

Radius, r = 0.25/2 = 0.125 m

Entry temperature, T₁ = 304 + 273 = 577 K

Exit temperature, T₂ = 284 + 273 = 557 K

Ambient temperature, \(T_a = 25^0 C = 298 K\)

Pipe length, L = 10 m

Area, A = 2πrL

A = 2π * 0.125 * 10

A = 7.855 m²

Mass flow rate,

\(\dot{ m} = 4.5 tons/hr\\\dot{m} = \frac{4.5*1000}{3600} = 1.25 kg/sec\)

Rate of heat transfer,

\(\dot{Q} = \dot{m} c_p ( T_1 - T_2)\\\dot{Q} = 1.25 * 1.005 * (577 - 557)\\\dot{Q} = 25.125 W\)

a) To calculate the convection coefficient relationship for heat transfer by convection:

\(\dot{Q} = h_c A (T_1 - T_2)\\25.125 = h_c * 7.855 * (577 - 557)\\h_c = 0.1599 W/m^2 - K\)

Note that we cannot calculate the heat loss by the pipe to the environment without first calculating the surface temperature of the pipe.

c) The surface temperature of the pipe:

Smear coefficient of the pipe, \(k_c = 0.8\)

\(\dot{Q} = k_c A (T_s - T_a)\\25.125 = 0.8 * 7.855 * (T_s - 298)\\T_s = 302 K\)

b) Heat loss from the pipe to the environment:

\(H_{loss} = h_c A(T_s - T_a)\\H_{loss} = 0.1599 * 7.855( 302 - 298)\\H_{loss} = 5.02 W\)

d) The required fan control power is 25.125 W as calculated earlier above

Answer:

Beam of 25" depth and 12" width is sufficient.

I've attached a detailed section of the beam.

Explanation:

We are given;

Beam Span; L = 20 ft

Dead load; DL = 0.50 k/ft

Live load; LL = 0.65 k/ft.

Beam width; b = 12 inches

From ACI code, ultimate load is given as;

W_u = 1.2DL + 1.6LL

Thus;

W_u = 1.2(0.5) + 1.6(0.65)

W_u = 1.64 k/ft

Now, ultimate moment is given by the formula;

M_u = (W_u × L²)/8

M_u = (1.64 × 20²)/8

M_u = 82 k-ft

Since span is 20 ft, it's a bit larger than the average span beams, thus, let's try a depth of d = 25 inches.

Effective depth of a beam is given by the formula;

d_eff = d - clear cover - stirrup diameter - ½Main bar diameter

Now, let's adopt the following;

Clear cover = 1.5"

Stirrup diameter = 0.5"

Main bar diameter = 1"

Thus;

d_eff = 25" - 1.5" - 0.5" - ½(1")

d_eff = 22.5"

Now, let's find steel ratio(ρ) ;

ρ = Total A_s/(b × d_eff)

Now, A_s = ½ × area of main diameter bar

Thus, A_s = ½ × π × 1² = 0.785 in²

Let's use Nominal number of 3 bars as our main diameter bars.

Thus, total A_s = 3 × 0.785

Total A_s = 2.355 in²

Hence;

ρ = 2.355/(22.5 × 12)

ρ = 0.008722

Design moment Capacity is given;

M_n = Φ * ρ * Fy * b * d²[1 – (0.59ρfy/fc’)]/12

Φ is 0.9

f’c = 4,000 psi = 4 kpsi

fy = 60,000 psi = 60 kpsi

M_n = 0.9 × 0.008722 × 60 × 12 × 22.5²[1 - (0.59 × 0.008722 × 60/4)]/12

M_n = 220.03 k-ft

Thus: M_n > M_u

Thus, the beam of 25" depth and 12" width is sufficient.

This question requires a thermal analysis of the heat exchanger system, which would involve the calculation of heat transfer rate and the resulting temperature change in both the light oil and the hot oil from the still bottom. This would require an understanding of heat transfer principles and the application of energy balance equations.

To determine the maximum temperature attained by the light oil in the heat exchanger, you would need to consider the flow arrangement of the two fluids, whether they are flowing in counter-current or co-current direction. This would affect the heat transfer rate and the resulting temperature change in each fluid.

To calculate the temperatures, you would need to consider the heat transfer rate between the two fluids, the inlet and outlet temperatures of each fluid, and their specific heat capacities. The equations would need to take into account the heat transfer rate, mass flow rate, and temperature change for each fluid.

Once the temperatures have been calculated, you can then determine the maximum temperature attained by the light oil and the hot oil, which would depend on the flow arrangement and the heat transfer rate between the two fluids.

It is recommended that you consult with a specialist in the field of thermal analysis or heat transfer to accurately and properly determine the maximum temperature attained by the light oil in the heat exchanger.

After three hours of rainfall/runoff, the mass of mud accumulated in the detention pond can be calculated by considering the flow rate and concentration of particles in the inflow water.

The concentration of particles in the creek after mixing with the overflow from the pond can be determined based on the flow rates and concentrations of the pond outflow and the ambient creek water.

To calculate the mass of mud accumulated in the detention pond after three hours of rainfall/runoff, we need to consider the flow rate and concentration of particles in the inflow water. The inflow water has a flow rate of 5.00 m^3/min and a particle concentration of 4000 mg/L. Since the rain is steady, we can assume a constant inflow rate over the three-hour period. By multiplying the inflow flow rate by the particle concentration and the duration (in minutes) of three hours, we can calculate the mass of mud accumulated in the detention pond.

To determine the concentration of particles in the creek after mixing with the overflow from the pond, we need to consider the flow rates and concentrations of the pond outflow and the ambient creek water. The pond outflow has a concentration of 400 mg/L and is a fraction of the inflow water that overflows into the creek. By adding the product of the pond outflow concentration and flow rate to the product of the ambient creek water concentration and flow rate, divided by the sum of the two flow rates, we can calculate the concentration of particles in the creek after mixing.

These calculations provide insights into the amount of mud accumulated in the pond and the resulting concentration of particles in the creek, allowing for an assessment of the effectiveness of the detention pond in mitigating pollution from soil particles in the runoff.

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.

Two kg of a two phase liquid vapor mixture of carbon dioxide (CO₂) exists at -40°C in a 0.05m³ tank. Determine the quality of the mixture, if the values of specific volume for saturated liquid and saturated vapor CO₂ at -40°C are \(v_{f}\) = 0.896 x 10⁻³m³/kg and \(v_{g}=\) 3.824 x 10⁻²m³/kg, respectively.

Answer: x = 1

Explanation: In a phase change of a pure substance, at determined pressure and temperature, the substance exists in two different phases: saturated liquid and saturated vapor.

Quality (x) is the ratio of saturated vapor in the mixture and can be written as:

\(x=\frac{m_{vapor}}{m_{liquid}+m_{vapor}}\)

It has value between 0 and 1: x = 0 for saturated liquid and x = 1 for saturated vapor.

When related with volumes, quality is rearranged as:

\(x=\frac{v-v_{f}}{v_{g}-v_{f}}\)

Solving for x:

\(x=\frac{0.05-0.896.10^{-3}}{3.824.10^{-2}-0.896.10^{-3}}\)

\(x=\frac{0.049104}{0.037344}\)

x = 1.3

Quality of mixture of carbon dioxide is x = 1, which means it's for saturated vapor.

To calculate the excavation and backfill for the attached trench, we first need to determine the excavation quantity of the earth and backfill stone. The last step is to calculate the backfill quantity of the earth.

Determination of the excavation quantity of the earth is done by measuring the length, width, and depth of the trench and multiplying these values together. For example, if the trench is 10 feet long, 2 feet wide, and 3 feet deep, the total excavation quantity would be 60 cubic feet of earth.

Next, we need to calculate the backfill stone. Assuming the pipe does not require a deduction, the backfill stone quantity is equal to the excavation quantity of earth. Therefore, for the example above, the total backfill stone quantity would be 60 cubic feet.

Finally, we need to calculate the backfill quantity of earth. This is done by subtracting the backfill stone quantity from the excavation quantity. In the example above, the backfill quantity of earth would be 0 cubic feet, since the backfill stone quantity is equal to the excavation quantity.
