A quantity of water with in 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 vapour. The vapour then expands adiabatically to a pressure of 5 bar while doing 364.31 kJ/kg of work.

(a) Sketch the cycle on p-v coordinates.

(b) Evaluate the heat transfer per unit mass and work per unit mass for each process, kJ/kg.
