EML 3015C Thermal-Fluid I Assignment 9 Fall 1999 Part 1. Isentropic Efficiency and Entropy Generation
Assignment 9-1: Steam enters the turbine steadily at 8 MPa and 400?C and leaves at a pressure of 1 MPa. Determine (a) the work output if the process is isentropic. If the actual turbine is operating at 70% isentropic efficiency, determine (b) the actual work output, (c) the actual exit temperature of the steam, (d) the entropy generation (assume adiabatic). Base your calculation on 1 kg/s of steady steam flow.
