Q3) A steam power plant operates on a simple ideal Rankine cycle between the pressures limits of 8000 kPa and 10 kPa. The mass flow rate of steam through the cycle is 25 kg/s. The temperature of steam at the turbine inlet is 400 C. Show the cycle on a block diagram and on a T-S diagram with respect to saturation lines. Calculate: a- The rate of heat input in the boiler and the rate of heat output in the condenser. b-The thermal efficiency of the turbine.
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.

A 8000 kW gas-turbine power plant operates with single stage compression, two-stageexpansion and with a reheating process. The high pressure turbine drives the compressor andthe low pressure turbine produces the net work output. Atmospheric air enters the compressorat 27 oC and the combustion gasses enter the high pressure turbine at 927oC. The combustiongasses leaving the high pressure turbine is reheated back to 827 oC before expanding in the lowpressure turbine. The overall pressure ratio is 9.
