A Stirling cycle operating with helium as working substance has a pressure of 80 psia, a temperature of 250F, and a specific volume of 3.28 ft^3/lb at the beginning and end of the isothermal heat rejection process. The ratio of volumes at the beginning and end of isothermal heat rejection is 2. The highest temperature involved in the cycles is 2200F. Calculate the following a. The heat supplied in BTU/lb b. The heat rejected in BTU/Ib c. The thermal efficiency
