Steam enters the turbine of a vapor power plant at 600 lbf/in.2, 700F and exits as a two-phase liquid-vapor mixture at 100F. Condensate exits the condenser at 95F and is pumped to 600 lbf/in. 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 lb/h. Steam enters the turbine of a vapor power plant at 600 lbf/in.2, 700F and exits as a two-phase liquid-vapor mixture at 100F.
