A boiler plant produces 40tonne of steam per hour for the turbine propulsion plant. This steam is at 6000kPa, 460°C. The turbine unit consists of 3 turbines HP, IP and LP. Between the HP and IP there is a reheater which isobarically raises the steam temperature to 440°C. The exhaust pressures of each turbine are 1000kPa, 200kPa and 4kPa respectively. The isentropic efficiencies of each turbine is 85%. Determine: (a). the condition of the steam at each exhaust (b). the power developed by the turbine plant (c). Rankine efficiency including the feed pump (d). specific steam consumption (e). heat removed from the condenser by the seawater per minute
