2010-12-8 · Consider an ideal steam reheat cycle where steam enters the high-pressure turbine at 4.0 MPa, 400 C, amd then expands to 0.8 MPa. It is then reheated to 400 C and expands to 10 kPa in the low-pressure turbine. Calculate the cycle thermal efficiency and the moisture content of the stea m leaving the low-pressure turbine.
