2. At the beginning of compression, an ideal Diesel cycle using air has a pressure of 15 psia, a temperature of 75 "F and a specific volume of 13.2 cubic feet per pound. For a compression ratio of 15 and a heat addition of 352 Btu/lb, calculate the following: a. the heat rejected b. the net work c. the thermal efficiency d. the horsepower developed by an ideal engine operating on the cycle and using 0.50 lb/s
