In a two stage turbine unit, constant pressure reheating is employed between the HP and LP stages The steam conditions are: 2500kPa, 300°C at HP inlet, 1200kPa at HP exhaust, 250°C after reheating and 4kPa at condenser inlet. The isentropic efficiencies for the HP and LP turbines are 0.78 and 0.75 respectively. Determine: (a). total power developed for a steam flowrate of 2.58kg/s (b). condition of the steam at the LP exhaust if the reheater is bypassed (c). the specific steam consumption with the reheater in service
