10-19 Consider a 210-MW steam power plant that operates on a simple ideal Rankine cycle. Steam enters the turbine at 10 MPa and 500°C and is cooled in the condenser

at a pressure of 10 kPa. Show the cycle on a T-s diagram with respect to saturation lines,and determine (a) the quality of the steam at the turbine exit, (b) the thermal efficiency of the cycle, and (c) the mass flow rate of the steam. Answers: (a) 0.793, (b) 40.2 percent, (c) 165 kg/s pressure limits of 25 and 200 psia. Assuming a mass flow rate of 14 lbm/s, determine (a) the thermal efficiency of the cycle, (b)the heat transfer rate in the regenerator, and (c) the power delivered.
