Find the specific turbine work from the extraction flow

Reference no: EM131250096

Find the specific turbine work from the extraction flow for the cycle in Problem 9.51 and the specific heat transfer in the boiler operating at 20 MPa, assuming the extraction flow goes through a drip pump and is added to the feed water line.

Problem 9.51

A closed FWH in a regenerative steam power cycle heats 20 kg/s of water from 100?C, 20 MPa to 200?C, 20 MPa. The extraction steam from the turbine enters the heater at 4 MPa, 275?C and leaves as saturated liquid. What is the required mass flow rate of the extraction steam?
