Air contained within a pistoncylinder assembly undergoes three processes in series:
a. Process 12: compression at constant pressure from P1=10lbf/in2, V1=4ft3 to state 2
b. Process 23:Consant volume heating to state 3, where P3=50lbf/in2
c. Process 31: Expansion to the initial state, during which the pressurevolume relationship is PV=constant.
Sketch the process in series on PV coordinates. Evaluate the (a) volume at state 2, in ft3, (b) work for each process, in Btu

Best ResponseYou've already chosen the best response.1Not actually sure what they want you to do there: the work from 1>2 is 10*(?4) but I don't see how the expect you to find the volume it's compressed to...
