The steam at a pressure of 100 bar and 500°C is supplied to a steam turbine. It comes out at 0.07 bar and 0.85 dry. One stage reheating is used and reheating is carried out upto its original temperature. Determine the theoretical thermal efficiency of the plant. Also find out the pressure at which reheating is carried out.

Question
The steam at a pressure of 100 bar and 500°C is supplied to a steam turbine. It comes out at 0.07 bar and 0.85 dry. One stage reheating is used and reheating is carried out upto its original temperature. Determine the theoretical thermal efficiency of the plant. Also find out the pressure at which reheating is carried out. Assume expansions at both stages are isentropic. Show the processes on T-s chart. If the net output is 1400 kJ/kg of steam find out the actual efficiency of the plant
