Answer:
A steam power plant operates on an ideal regenerative Rankine cycle. Steam enters the turbine at and and is condensed in the condenser at . Steam is extracted from the turbine at to heat the feed water in an open feed water heater. Water leaves the feed water heater as a saturated liquid. Show the cycle on a -s diagram, and determine ( ) the net work output per kilogram of steam flowing through the boiler and ( ) the thermal efficiency of the cycle.
