Steam enters the turbine of a vapor power plant at 600 Ibf/in.^2, 1000°F and exits as a two phase liquid-vapor mixture at 80°F.Condensate exits the condenser at 75°F and is

pumped to 600 lbf/in.2 The turbine and pump isentropic efficiencies are 90 and 80%.respectively. The net power developed is 1 MW. Determine: (a) the percent steam quality at the turbine exit. (b) the percent thermal efficiency, (c) the steam mass flow rate, in Ib/h.
