university of north carolina Operations And Supply Chain Management Assignment Help - The temperature

Question - A steam power plant operates on the reheat regenerative Rankine cycle with a closed feedwater
heater. Steam enters the turbine at 12.5 MPa and 550°C at a rate of 24 kg/s and is condensed in the
condenser at a pressure of 20 kPa. Steam is reheated at 5 MPa to 550°C. Some steam is extracted
from the low-pressure turbine at 1.0 MPa, is completely condensed in the closed feedwater heater,
and pumped to 12.5 MPa before it mixes with the feedwater at the same pressure. Assuming an
isentropic efficiency of 88 percent for both the turbine and the pump, determine
(a) The temperature of the steam at the inlet of the closed feedwater heater,
(b) The mass flow rate of the steam extracted from the turbine for the closed feedwater heater,
( ...Read More c) The net power output, and
(d) The thermal efficiency. ...Read Less
