A steam turbine operates on a Carnot cycle, with a maximum pressure of 20 bar and a condenser pressure of 0.5 bar. Calculate the salient points of the cycle, the energy addition and work output per unit mass, and hence the thermal efficiency of the cycle.Compare this value to the Carnot efficiency based on the temperatures of energy addition and rejection. [26.98%; 27.0%]
