Question:

A power plant operates on a regenerative vapor power cycle with one closed feed water heater. Steam enters the first turbine stage at 7 MPa, 550oC and expands to 700 kPa, where some of the steam is extracted and diverted to a closed feed water heater. Condensate exiting the feed water heater as saturated liquid at 700 kPa passes through a trap into the condenser. The feed water exits the heater at 7 MPa with a temperature of 175oC. The condenser pressure is 8 kPa. If the power developed is 100 MW, determine
(a) The thermal efficiency (ηth) of the cycle and
(b) The mass flow rate into the first stage turbine.
