Consider a simple ideal Rankine cycle which uses water as the working fluid. The net power of power plant is 220-MW. At the turbine inlet, steam is at 9 MPa and 560°C. The condenser pressure is 20 kPa. Determine the following values.
The temperature at the pump inlet.
°CThe specific enthalpy at the pump inlet.
kJ/kgThe specific volume at the pump inlet.
m3/kgThe pump work.
kJ/kgThe temperature at pump exit.
°CThe specific entropy at turbine inlet.
kJ/kg·KThe quality of steam at turbine exit.
The temperature of steam at turbine exit:
°C. Now using calculated T and s values draw a T-s diagram to compare with the one in notes or textbook. You may use the plot_TS_water function. The thermal efficiency of the cycle.
%
The mass flow rate of the steam.
