Question
Steam enters the turbine of a vapor power plant at 600 lbf/in.?, 700°F and exits as a two-phase liquid-vapor mixture at 90°F.
Condensate exits the condenser at 85°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.
