10.9_An ideal vapor compression refrigeration system operates at steady state with Refrigerant 134a as the working fluid. Superheated vapor enters the compressor at 30 lbf/in2 , 20 ◦F, and saturated liquid leaves the condenser at 140 lbf/in2 . The refrigeration capacity is 5 tons. Determine a) The compressor power, in horsepower. b) The rate of heat transfer from the working fluid passing through the condenser, in Btu/min. c) The coefficient of performance. Modify the cycle in Problem 10.9 to have an isentropic compressor efficiency of 85% and let the temperature of the liquid leaving the condenser be 95 ◦F. Determine, for the modified cycle, a) The compressor power, in horsepower. b) The rate of heat transfer from the working fluid passing through the condenser, in Btu/min. c) The coefficient of performance d) The irreversibility rates of the compressor and expansion valve, each in Btu/min, for T0 = 80 ◦F

5. A company is considering a project that will require an investment today of $1,700,000. It will produce an after-tax cash flow of $136,000 in year one, an amount that will grow at 4% per year forever. The required rate of return for this project is 11%. a. What is the net present value for this project? Should the project be done? b. What would the net present value be if the after tax cash flows never grow (i.e. remain constant)? Should the project be done in this case? c. What is the minimum rate of growth in the after tax cash flows required to justify doing this project?
