Steam enters a turbine with an isentropic efficiency of 83.0% at 300 psia, 800°F and exhausts to a condenser at 0.250 psia. The boiler feedwater is heated in a single, open loop regenerator with steam extracted from the turbine at 100 psia. Saturated liquid leaves the regenerator at the pressure of the extraction steam. Neglecting all pump work determine:

a. The percent mass flow of steam extracted from the turbine.
b. The turbine power output per unit mass flow of steam.
c. The system thermal efficiency.
d. The turbine power output per unit mass flow of steam when the regenerator is not in use.
e. The system thermal efficiency when the regenerator is not in use.
f. The percent increase in system thermal efficiency produced by the regenerator.
