Mechanical Engineering

In a non-ideal Rankine cycle saturated vapor (x=1) enters theturbine at 8.0 MPa and saturated liquid water (x=0) exits thecondenser at a pressure of Pexit. Pexit = 0.006 MPa. The net poweroutput of the cycle is given as 100 MW. Knowing that the isentropicefficiency of the pump is 0.85 generate the following plotsin Excel or in similar programs for the given range of theisentropic efficiency of the turbine. (Please submit your Excelsheet or your computer program with the homework.)

a) Isentropic efficiency of the turbine 0.7 <?T < 0.9 vs. steam mass flow rate

b) Isentropic efficiency of the turbine 0.7 <?T < 0.9 vs. Rate of heat transfer from theboiler to the compressed water at the outlet of the pump

c) Isentropic efficiency of the turbine 0.7 <?T < 0.9 vs. thermal efficiency of thecycle
