A horizontal piston assembly contains water. The piston is connected to a shaft, which can apply different forces to the piston as the water is expanded or compressed. Initially the apparatus contains a saturated liquid-vapor mixture of water at .9 bar with quality of 80% and a volume of 1.0 m^3. The shaft is programmed to move following a polytropic processs until the volume doubles and the pressure is 0.7 bar.

A) For the initial state, what percent of the total volume is occupied by vapor?

B) Could Kinetic and potential effects be neglected for the system? Why or Why not?

C) Determine the amount of heat transfer required to accompany the process in kJ

D) For the initial state, calculate the amount of mass present in the vapor phase kg

E) Determine the type of polytrophic process (find n when PV^n= Constant

You are considering starting a company that manufactures racing bicycles. You are planning on financing your firm 40% equity and 60% debt. You estimate that your upfront costs will be $5M, and that you will earn an EBIT of $1M per year for the next 12 years.

Lightning Bolt Bikes makes racing bicycles similar to the ones that you wish to manufacture. They have a CAPM equity beta of 1.9 and a debt to equity ratio of 0.7. The tax rate for both firms is 35%, the riskless rate is 3%, and the expected return on the S&P500 is 15%

A.What is the asset beta of Lightning Bolt Bikes and your unlevered cost of equity?

B. What is your firm’s equity beta?

C. What is your firm's weighted average cost of capital?

D. Use WACC method to find NPV of your proposed bicycle company?

Plant Food Case

A garden center wishes to determine if there are in fact differences in the effect of three different brands of plant food on the growth of sunflowers and the rank of their effectiveness in promoting growth. To do so, they selected 15 sunflower seedlings at random from the greenhouse and fed 5 of the seedlings with Plant Food A, 5 with Plant Food B, and 5 with Plant Food C. The weekly growth of each seedling was measured in inches and is summarized below.

1. Describe the purpose of the study
