Consider an ideal Rankine cycle with a single open feed water heater. The boiler pressure is 800 psia, and the condenser pressure is 2 psia. Steam is extracted from the turbine to heat the feed water at 90 psia. Steam enters the turbine at 1000F. Find the following:
a. The fraction of steam extracted for feed water heating
b. The quality of the steam exiting the turbine and entering the condenser
c. The net specific work of the cycle
d. The thermal efficiency of the cycle
