Asystem consisting of 1 kg of water undergoes a power cycle composed of the following processes:

process 1-2: constant pressure heating from p1=10 bar, t1=179.9oc, to t2=562.6oc. assume the water is saturated vapor at state 1.

process 2-3: constant volume cooling to p3=5 bar.

process 3-4: isothermal compression with q3-4=-815.6 kj.

process 4-1: constant volume heating to p1=10 bar, v4=v1.

part a) draw the p-v diagram and label all pressures and volumes with units.

part b) determine the thermal efficiency for the cycle.
