Energy addition in polytropic process: In this case, the initial (air) pressure is 750 psia and 750 F. The polytropic process is pv^1.5 = constant. The final air temperature is 3000 F.
a) What is the boundary work associated with this process? Report your answer in Btu.?
Consequently, the only way to alter the system energy, E, is through work, W, and heat transfer, Q. In this case: PV^1.5=constant. The initial state is 1500 psia and 200 F. The final state is 150 psia.
b) In the absence of any heat transfer compute the change in air energy. Report your answer in ft-lbf/lbm.
c) Given the information given above can you make any statements as to the fraction of system energy that exists as internal energy, as kinetic energy or as potential energy.
