Consider a steam power plant that operates on a reheat Rankinecycle and has a net power output of 80 MW.
Steam enters the high-pressure turbine at 10 MPa and 500°C and thelow-pressure turbine at 1 MPa and 500°C. Steam leaves the condenseras a saturated liquid at a pressure of 10 kPa. The isentropicefficiency of the turbine is 80 percent, and that of the pump is 95percent. Show the cycle on a T-s diagram with respect to saturationlines, and determine (a) the quality (or temperature, ifsuperheated) of the steam at
the turbine exit, (b) the thermal efficiency of the cycle, and (c)the mass flow rate of the steam.k
