Two kilograms of water execute a Carnot power cycle. During the isothermal expansion, the water is heated until it is a saturated vapour from an initial state where the pressure is 40 bar and the quality is 15%. The vapour then expands adiabatically to a pressure 1.5 bar while doing 491.5 kJ/kg of work. Sketch the cycle on P-v coordinates Evaluate the heat and work for each process, in kJ Evaluate the thermal efficiency.
