Find the mass fraction extracted in the turbine

Reference no: EM131250002

Consider the power plant in Problem 9.41. Assume that the high temperature source is a flow of liquid water at 120?C into a heat exchanger at constant pressure, 300 kPa and that the water leaves at 90?C. Assume that the condenser rejects heat to the ambient, which is at -20?C. List all the places that have entropy generation and find the entropy generated in the boiler heat exchanger per kilogram of ammonia flowing.

Problem 9.41

A power plant for a polar expedition uses ammonia and the boiler exit is 80?C, 1000 kPa, and the condenser operates at -15?C. A single open FWH operates at 400 kPa with an exit state of saturated liquid. Find the mass fraction extracted in the turbine.
