Question:

Steam is the working fluid in an ideal Rankine cycle with superheat and reheat. Steam enters the first stage turbine at 10 MPa, 500oC and expands to 700 kPa. It is then reheated to 450oC before entering the second stage turbine, where it expands to the condenser pressure of 8 kPa. The net power output is 100 MW. Determine
(a) The rate of heat transfer from the condensing steam as it passes through the condenser.
(b) The thermal efficiency (ηth) of the cycle,
(c) The mass flow rate of steam and
