Steam enters the high-pressure turbine of a rankine cycle, Ask an Expert

Academics

Steam enters the high-pressure turbine of a Rankine cycle power plant at 1200. psia and 700.°F and exits as a saturated vapor. It is then reheated to 600.°F before it enters the low-pressure turbine, which exhausts to a condenser at 1.00 psia.

The isentropic efficiencies of the high- and low-pressure turbines and the boiler feed pump are 88.0%, 79.0%, and 65.0%, respectively. Determine the thermal efficiency and the net power per unit mass flow rate of steam for this plant.
