Question:
Please solve this problem of a standard air cycle with a piston. Treat air as ideal. Specific heat of air is cv and cp=cv+Rair.
The pressure and temperature at the beginning of compression are p1 = 100kpa and t1 = 300K.
Qin/m = 1500 kj/kg. 1/3 of the heat added per unit mass is under constant press. while 2/3 are add under constant volume. Approx heat rej. as a constant vol. process.
Sketch the process in a PV diagram
Then find T and P of each of the 5 states in terms of cv and cp
Calculate thermal efficiency of the modified cycle
