Steam is expanded in the high pressure turbine from 4000kPa, 360°℃ to 1000kPa with an isentropic efficiency of 80%. The steam is then reheated isobarically to 360°C after which it passes through the low pressure turbine expanding down to 4kPa with an isentropic efficiency of 75%. If the condensate has a temperature of 24°C, calculate: (a). the condition of the steam entering the reheater (b). the condition of the steam entering the condenser (c). the total power output for a mass flow-rate of 10tonnes of steam per hour (d). the specific steam consumption in kg steam/kWh (e). the Rankine efficiency of the plant including the feed pump work
