A quantity of water within a piston–cylinder assembly executes a Carnot power cycle. During isothermal expansion, the water is heated from saturated liquid at 50 bar until it is a saturated vapor. The vapor then expands adiabatically to a pressure of 5 bar while doing 364.31 kJ/kg of work. (a) Sketch the cycle on p–y coordinates. (b) Evaluate the heat transfer per unit mass and work per unit mass for each process, in kJ/kg. (c) Evaluate the thermal efficiency.
