Discuss the below:
Q: Air initially at 100 psia, 500 F undergoes an internally reversible process to 45 psia. For each of the following cases, determine for 10 lbm of air the heat transfer and work, each in Btu, and show the processes on P-v and T-s coordinates.
The process is:
a) Isothermal
b) Adiabatic (Hint: look at other assumptions above)
c) Constant volume
