A power cycle operating on 2kg of ideal argon (a closed thermodynamic system) consists of 3 parts:
A reversible isochore from an equilibrium state at P1= 1 bar, t1=100C to an equilibrium state at t2=300C followed by a adiabatic isentropic expansion to P3=1 bar, followed by a reversible isobaric compression back to state 1. Find the thermal efficiency of the cycle. Sketch the P-v and T-s diagrams of the cycle.
