The power plant in Problem 9.16 has too low a quality in the low-pressure turbine section, so the plant wants to apply reheat at 800 kPa. What should the superheat for the reheat be so that the turbine quality stays above 92%?
Problem 9.16
A utility runs a Rankine cycle with a water boiler at 3.0 MPa, and the cycle has the highest and lowest temperatures of 450?C and 60?C, respectively. Find the plant efficiency and the efficiency of a Carnot cycle with the same temperatures.
