Water enters the boiler of a steady-flow Carnot engine as a saturated liquid at 300 psia and leaves with a quality of 0.95. Steam leaves the turbine at a pressure of 20 psia. Show the cycle on a T-s diagram relative to the saturation lines, and determine

(a) The thermal efficiency

(b) The quality at the end of the isothermal heat-rejection process

(c) The net work output.
