2. Water at a temperature of 80 °C and velocity of 1.2 m/s is flowing parallel to one side of a smooth flat plate. The plate is maintained at a constant temperature of 24 °C and is 0.8 m long and 0.5 m wide. Determine the following:

1. The heat flux at a distance x = 0.6m from the front edge of the plate, q” = ____________
2. The location of the maximum heat flux on the plate, x = _________
3. The total convective heat transfer from the water to the top surface of the plate,

                                                                                                                   q = __________

4. The convective heat transfer between the water and the plate from x = 0.6 m to x = 0.8m

                                                                                                                   q₂ = __________

for water: ρ = 987 kg/m³, µ = 528 x 10^-6 N·s/m², k = 645 x 10^-3 W/m·K, Pr = 3.42

A regenerative Rankine cycle operates with inlet conditions of 800°C and 5MPa and exhausts to a pressure of 10kPa. A single open-feedwater heater is used with an extraction pressure of 0.8 MPa. Assume the exit states of the condenser and the feedwater heater are both saturated liquids. The turbine and pump isentropic efficiencies are 100%.

1. Draw the T-s diagram and determine the thermal efficiency for the cycle and the total turbine work per unit boiler mass flow rate (kJ/kg)
2. Repeat the problem in part 1, but replace the open feed water heater with a closed feed water heater where the extracted steam is pumped to the boiler pressure before being combined with the condenser feed water
3. Repeat the problem in part 2, but where the extracted steam is throttled from the closed feed water heater exit to the condenser

The total value of your portfolio is $10,000: $3,000 of it is invested in Stock A and the remainder invested in Stock B. Stock A has a beta of 0.8; Stock B has a beta of 1.2. The risk premium on the market portfolio is 8%; the risk-free rate is 2%. Additional information on Stocks A and B is provided below.

1. What are each stock’s expected return and the standard deviation?
2. What are the expected return and the standard deviation of your portfolio?
3. What is the beta of your portfolio?
4. 1. Using CAPM, what is the expected return on the portfolio?
   2. Given your answer above, would you buy, sell, or hold the portfolio?

. Complete the following:

a. If the tax multiplier is -1, then the marginal propensity to save is _________ the marginal propensity to consume.

b. If the government spending multiplier is 8, then the marginal propensity to save equals______.

c. If the marginal propensity to consume is two times the marginal propensity to save, then the government spending multiplier equals _______.

d. If the marginal propensity to save is 0.5, then the tax multiplier equals _______.

e. If the marginal propensity to save increases by 10 percent, then the government spending multiplier ________.

f. If the marginal propensity to consume goes from 0.8 to 0.85, then the tax multiplier _________.

g. If the tax multiplier increases (in absolute value) from -1 to -2, this means that the marginal propensity to consume has ______ relative to the marginal propensity to save.

h. If the government spending multiplier decreases from 5 to 4, this means that the marginal propensity to save has _______.

Consider two economies. In economy A: autonomous consumption equals 700, the marginal propensity to consume equals 0.80, taxes are fixed at 50, investment is 100, government spending is 100, and net exports are 40.

In economy B: autonomous consumption equals 1000, the marginal propensity to consume equals 0.8, taxes are proportional to income such that consumers pay 25% of their income as taxes, investment is 250, government purchases are 150, and net exports are 400.

(i) What is the planned aggregate expenditure (PAE) in each economy?

(ii) What is the short-run equilibrium output in each economy?

(iii) In which economy is the spending multiplier higher?

(iv) Suppose autonomous consumption fall by 500 in each economy. Which economy will see a higher drop in GDP? Compute the equilibrium output in each economy.

You proposed a portfolio for your client with 60% in stock A and 40% in stock B. Stock A has an average weekly return of 0.88% and stock B has an average weekly return of 1.32%. Beta for stock A and B are 0.8 and 1.3 respectively. Now you want to deliver a performance report to the client regarding portfolio performance on a weekly basis. (a). What’s the portfolio average weekly return?

(b). What’s the portfolio beta?

(c). You have calculated the portfolio weekly standard deviation: 3.9%. What’s the Sharpe ratio of the portfolio? Assuming weekly market return is 0.9% and weekly riskfree rate is 0.04%.

(d). Still assume the portfolio weekly standard deviation is 3.9%, weekly market return is 0.9% and weekly risk-free rate is 0.04%, what’s Jensen’s Alpha of the portfolio?
