Steam enters the turbine of a vapor power plant at 600 lbf/in.2, 1000°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 lb/h.

Question

Steam enters the turbine of a vapor power plant at 600 lbf/in.2, 1000°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 lb/h.
