iii) Steady reversible and adiabatic(isentropic) compression of air (ideal gas) from 1 bar to 3bar at a mass
flow rate of m = 1 kg/s(Pvk= const. where k = cp/cv) Take the inlet temperature of air as T=300 K
a) Draw in EXCEL the P-v diagrams for each of the steady, reversible processes in the SAME plot
b) Calculate the work requirement for each of the processes. Order the processes according to the
work requirements
