Question

Please provide the complete solution for the Pm. Thank you!

QA = 346.320 BTU

QR = -208.981 BTU

V4 = 31.818 ft^3

V2 = 18 ft^3

 

 

The working substance for a Carnot cycle is 8 lb of air. The volume at the beginning of
isothermal expansion is 9 cu ft and the pressure is 300 psia. The ratio of expansion during
the addition of heat is 2 and the temperature of the cold body is 90°F.
Find:
Pm (Mean Effective Pressure) in Psia
