Question
The net power of a steam power plant operating on the simple ideal Rankine cycle is 30.5 MW. Water vapor enters the turbine at a pressure of 7 MPa and a temperature of 500 °C, expanding to a condenser pressure of 10 kPa in the turbine. The steam is condensed in the condenser by cooling with water supplied from a lake. The flow rate of the lake water is 1950 kg/s. Get 87% of pump and turbine adiabatic efficiencies. Show the cycle in the T-s diagram.
( Cwater=4.18 kj/kg°C )
a) Calculate the thermal efficiency of the cycle.
b) Calculate the flow of steam circulating in the loop.
c) Calculate the temperature rise of the coolant.
