In a steam power plant operating according to the ideal reheated Rankine cycle, water vapor enters the high pressure turbine at 6MPa pressure and 500 °C temperature and exits as saturated steam. The steam is then heated to 450 °C and expanded to 7.5 kPa in the low pressure turbine. The heat power given to the steam in the boiler is 60 MW. Cooling of the steam in the condenser is carried out by using a nearby stream, and the cooling water enters the condenser at a temperature of 7°C. a) Show the cycle on the T-s diagram, which also includes the saturated liquid and saturated vapor curves. b) By writing all the mass, energy, entropy and exergy balance equations, c) The pressure at which intermediate heating is carried out, d) Net power and thermal efficiency of the cycle, e) Calculate the minimum required cooling water flow rate. f) Taking the source temperature as 1600 K and the well temperature as 285 K, calculate the exergy destruction associated with the phase change in which heat enters the cycle. g) Also determine the exergy of the steam at the boiler exit.
