Consider a steam power plant that operates on a reheat Rankine cycle and has a net power output of 80 MW. Steam enters the high-pressure turbine at 10 MPa and 500°C and the low-pressure turbine at 1 MPa and 500°C. Steam leaves the condenser as a saturated liquid at a pressure of 10 kPa. The isentropic efficiency of the turbine is 80 percent and that of the pump is 95 percent. Show the cycle on a T-s diagram with respect to saturation lines, and determine:
a. The quality (or temperature, if superheated) of the steam at the turbine exit.
b. The thermal efficiency of the cycle.
c. The mass flow rate of the steam.
