Question

Hello, please help with this question for review purposes cuz my prof didn't teach us anything.

2. At the beginning of the compression stroke and ideal Otto cycle has an air pressure of 15 psia, a
temperature of 75° F and a specific volume of 13.2 ft /lb. At the end of compression the specific
volume is 1.76 ft/lb. The heat supplied to the cycle is 352 Btu/lb. Calculate the following:
A). the compression ratio
B). the highest temperature and pressure of the cycle
C).the temperature and pressure at the end of expansion of the air
D).the heat rejected, Btu/lb
E). the net work of the cycle, Btu/lb
F). the thermal efficiency of the cycle, %
G).the horsepower developed by an ideal engine operating on this
cycle using 0.5 pound of air per second.
