A steam power plant operates on an ideal reheat Rankine cycle between the pressure limits of 15 MPa and 10 kPa. The mass flow rate of steam through the cycle is 12 kg/s. Steam enters both stages of the turbine at 500C. If the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, determine (a) the pressure at which reheating takes place, (b) the total rate of heat input in the boiler, and (c) the thermal efficiency of the cycle. Also, show the cycle on a T-s diagram with respect to saturation lines.

Question
A steam power plant operates on an ideal reheat Rankine
cycle between the pressure limits of 15 MPa and 10 kPa.
The mass flow rate of steam through the cycle is 12 kg/s.
Steam enters both stages of the turbine at 500C. If the moisture
content of the steam at the exit of the low-pressure turbine
is not to exceed 10 percent, determine (a) the pressure at which
reheating takes place, (b) the total rate of heat input in the
boiler, and (c) the thermal efficiency of the cycle. Also, show
the cycle on a T-s diagram with respect to saturation lines.
