b) TNB steam power plant in Cameron Highlands operates on reheat Rankine cycle and has power net output of 45 MW. Steam enters the turbine at a MPa and b °C and it is cooled in the condenser at a pressure of c kPa by running cooling water from the Bertam River through the tubes of condenser. Steam enters both stages of the turbine at 500°C. If the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, show the cycle on a T-s diagram and determine; i. The pressure at which reheating takes place, ii. The thermal efficiency of the cycle and iii. Please justify how does the thermal efficiency of the cycle if the temperature to low turbine is increase to 600°C?
