When the transportation of natural gas in a pipeline is not feasible for economic reasons, it is first liquefied using nonconventional refrigeration techniques and then transported in super-insulated tanks. In a natural gas liquefaction plant, the liquefied natural gas (LNG) enters a cryogenic turbine at 30 bar and –160°C at a rate of 20 kg/s and leaves at 3 bar. If 120 kW power is produced by the turbine, determine the efficiency of the turbine. Take the density of LNG to be 423.8 kg/m3.

Answer:

they were updated rather than being created

Answer:

Invention is about creating something new, while innovation introduces the concept of “use” of an idea or method.

a)  The initial and final temprature are 99.61°C and T3 = 259.07°C

b)   The mass of liquid water when the piston first start moving is 0g

Using the data provided:

Initial Pressure = P1 = 125kPa

Mass of Saturated Vapor Liquid = m = 5kg

Initial Mass of Liquid water = mf = 2kg

Initial Mass of Vapor = mg = 3kg

The temperature for a mixture of liquid steam saturated with water according to the thermodynamic table is:

T₁ = 99.61°C

The specific volume is:

vf = 0.001043m³/kg

And the saturated volume is:

vg = 1.6941m³/kg

Therefore, the volume in state 1 will be equal to:

V1 = mfvf + mgvg

V1 = (2kg)(0.001043m³/kg) + (3kg)(1.6941m³/kg)

V1 = 5.084m³

In state 3 then the volume will be equal to:

V3 = 1.2V1

V3 = 1.2(5.084m³)

V3 = 6.1008m³

Then the specific volume will be equal to:

v3 = V₃/m

v3 = 6.1008m³/5kg

v3 = 1.2202m³/kg

For a pressure of 300 kPa and the previous specific volume found through the thermodynamic table, the value of the temperature is:

T3 = 259.07°C

Question b) When the piston first stats moving at P₂ = 300kPa and V₂ = V₁ = 5.084m³

v₂ =V₂/m

v₂ = 5.084m³/5kg

v2 = 1.0168m³/kg

While at 300 kPa the value of the vapor saturated vg = 0.88578m³/kg This implies that the condition is met:

v2 > vg

Therefore, no liquid is there in-cylinder when piston stats moving, mf = 0kg

Real options provide flexibility to the firm and help in managing risks associated with the capital project.

A. Calculation of initial, annual, and terminal after-tax cash flows:

Calculation of initial cash flow:

= (-) Cost of equipment + (+) Import duties + (+) Installation and testing cost + (+) Net working capital

= (-) $950,000 + (+) $19,000 + (+) $15,000 + (+) $29,000

= $13,000

Annual after-tax cash flows:

Initial cash outflow: $13,000

Annual cash inflow: $300,000

Tax rate: 25%

Calculation of annual cash flow (after-tax):

= Annual net operating cash inflow * (1 - Tax rate)

= $300,000 * (1 - 0.25)

= $225,000

Terminal after-tax cash flows:

Scrap value: $25,000

Tax rate: 25%

Calculation of terminal after-tax cash flow:

= Scrap value * (1 - Tax rate)

= $25,000 * (1 - 0.25)

= $18,750

B. The formula to calculate NPV is:

NPV = - Initial investment + PV of net cash flows

For calculating the NPV, we need to calculate the present value (PV) of net cash flows. The formula to calculate PV of net cash flows is:

PV of net cash flows = (Cash flow / (1 + r)^t)

Where:

r = cost of capital

t = time period

NPV = - $13,000 + $225,000 / (1 + 0.16) + $225,000 / (1 + 0.16)^2 + $225,000 / (1 + 0.16)^3 + $225,000 / (1 + 0.16)^4 + $225,000 / (1 + 0.16)^5 + $225,000 / (1 + 0.16)^6 + $225,000 / (1 + 0.16)^7 + $225,000 / (1 + 0.16)^8 + $18,750 / (1 + 0.16)^8

NPV = $33,706.39

As NPV is positive, it indicates that the installation of new equipment will increase the value of the firm. Thus, Happy Limited should invest in the new equipment.

C. Real options that may serve to reduce the risk of a capital project are as follows:

1. Option to abandon: The firm has the option to abandon the project if the outcomes are not as expected. This option helps to reduce the downside risk by allowing the firm to cut its losses and avoid further investment if the project is not performing well.

2. Option to expand: The firm has the option to expand the project if the outcomes are favorable. This option helps to capture the upside potential and reduce the risk by allowing the firm to invest more in the project if it is generating positive returns.

We must first ascertain the responses at point C as a result of the applied load P. As a result of the frame being in equilibrium, all forces operating on it must be zero in total. Hence, we have

Equilibrium, which is characterised as motion without linear or rotational acceleration, requires the fulfilment of two requirements. The net external force acting on the system must be zero in order for equilibrium to occur, or net F to equal 0.

Assuming that the temperature change is T = 50°C and that the wires are originally at room temperature (20°C), we have:

ΔL = αLΔT = 1210⁻⁶ ×L ×50 = 610⁻⁴ ×L (4)

Δθ = ΔL / r (5) (5)

We may calculate r using the geometry of the frame as follows: r = 2/3 ×L ×sin(30°) = 0.577×L (6)

The cost-benefit analysis would consider the potential risks associated with the development of the bicycle frame.

In a cost-benefit analysis for the development of a bicycle frame, considering risks involves assessing the potential negative outcomes or uncertainties that could impact the project's success. The analysis would factor in the likelihood of risks occurring and their potential impact on the cost and benefit aspects of the project.

For example, when aiming for a lighter and stronger bicycle frame, the engineering team may face risks such as difficulties in achieving the desired weight-to-strength ratio, encountering manufacturing challenges, or facing unforeseen design flaws during testing. These risks could lead to cost overruns, delays in production, or a lower-quality product.

To factor in risks, the analysis would identify and assess these potential risks, quantifying their impact on the project's cost and benefit. This assessment might involve estimating the cost of mitigating or managing the risks, such as investing in additional research and development, implementing quality control measures, or conducting thorough testing.

The team would then weigh the potential benefits against the potential costs, considering the likelihood of risks materializing and their potential consequences.

If the benefits outweigh the estimated costs, even considering the risks, the project may be deemed viable. However, if the risks pose significant threats to the project's success or the cost of managing the risks outweighs the expected benefits, the project may be deemed too risky or financially unviable.

In summary, factoring in risks in the cost-benefit analysis involves assessing potential negative outcomes, estimating their impact on cost and benefit, and determining whether the benefits outweigh the costs, considering the risks involved in developing the bicycle frame.

The efficiency of the transformer on full load is 94.92%.

Efficiency of the transformer is the ratio of output power to input power.

Efficiency = (Output Power / Input Power) x 100%

The input power to the transformer is given as Input Power = Output Power + Transformer Losses. The transformer losses can be categorized as copper losses and iron losses.

Copper losses are caused by the resistance of the winding, and are proportional to the square of the current flowing through the winding. On the other hand, iron losses are caused by the magnetization and demagnetization of the core laminations, and are proportional to the frequency of the applied voltage.

Let's determine the copper losses for both the primary and secondary winding of the transformer.

Copper Losses in Primary Winding:

\(P_p = I_p^2 * R_p = (KVA / V_p)^2 * R_p\)

    \(= (400 / 5000)^2 * 0.5\)

    \(= 0.016 KW = 16 W\)

Copper Losses in Secondary Winding:

\(P_s = I_s^2 * R_s\)

    \(= (KVA / V_s)^2 * R_s\)

    \(= (400 / 320)^2 * 0.001\)

    \(= 0.025 KW = 25 W\)

Iron losses for the transformer = 2.5 KW.

The Input power to the transformer at full load = Output Power + Transformer Losses = 400 KVA x 0.85 + 16 + 25 + 2.5 = 358.5 KW.

We know that Efficiency of the transformer is the ratio of output power to input power. Efficiency = (Output Power / Input Power) x 100%.

Efficiency of transformer on full load = 340 / 358.5 x 100% = 94.92%.

Therefore, the efficiency of the transformer on full load is 94.92%.

The volume flow rate of air through the venturi meter is approximately 69.4 cubic feet per second.

To determine the volume flow rate of air flowing through the venturi meter, we can use the principle of conservation of mass.

Since air is an incompressible fluid, the mass flow rate at location 1 (entrance) must be equal to the mass flow rate at location 2 (throat).

Therefore, we can express the volume flow rate Q as:
\(Q = A_1V_1\)

= \(A_2V_2\)
where \(A_1\) and \(A_2\) are the cross-sectional areas of the entrance and throat respectively, and \(V_{1}\) and \(V_{2}\) are the velocities of air at the two locations.

To calculate the velocities, we can use Bernoulli's equation which states that the sum of the pressure,

kinetic energy and potential energy per unit mass of a fluid is constant along a streamline.

Neglecting potential energy and kinetic energy changes (since the diameter changes only slightly), we have:
\(P_1 +\frac{1}{2}\)ρ\(V_1^2 = P2 + \frac{1}{2}\)ρ\(V_2^2\)
where \(P_1\) and \(P_2\) are the pressures at the entrance and throat respectively, and ρ is the density of air.

Rearranging this equation, we get:
\(V1 = \sqrt(\frac{2\times (P_1 - P_2)}{/\rho} ) \times (\frac{A_2}{A_1)}^2\)

Substituting the given values, we get:
\(V1 = \sqrt\frac{(2\times (12.2 - 11.8)}{(144*0.0765))} \times \frac{(1.8}{2.6)}^2\)
  ≈ 37.4 ft/s
Using the equation for volume flow rate, we get:
\(Q = A_1V_1\)

\(= \pi \times (\frac{2.6}{2})^2\times 37.4\)
