Analyzing Rankine Cycles

Steam enters the turbine of a simple vapor power plant with a pressure of 10 MPa and temperature T, and expands adiabatically to 6 kPa. The isentropic turbine efficiency is 85%. Saturated liquid exits the condenser at 6 kPa and the isentropic pump efficiency is 82%.

(a) For T = 580°C, determine the turbine exit quality and the cycle thermal efficiency.


(b) Plot the quantities of part (a) versus T ranging from 580 ft to 700°C.
