Two kilograms of water execute a carnot power cycle inside, Ask an Expert

Academics

Two kilograms of water execute a Carnot power cycle inside a piston-cylinder device. During isothermal expansion, water is heated from an initial state where its pressure is 40 bar and the quality is 15% (state 1) until its state is saturated vapor (state 2). The saturated vapor then expands adiabatically to a pressure of 1.5 bar (state 3) while 491.5 kJ/kg of work output is produced. Water is then isothermally compressed at 1.5 bar to state 4 and then via adiabatic compression back to state 1.

(a) Determine the heat transfer (kJ) and work (kJ) for each process.

(b) What is the thermal efficiency of this cycle?
