A steam powerplant operating on an ideal Rankine Cycle is operating at a boiler pressure of 5.75MPa, steam enters the turbine at 500°C and expands to 147kPa. If the powerplant is producing 5MW of energy find the following:
A steam powerplant operating on an ideal Rankine Cycle is operating at a boiler pressure of 5.75MPa, steam enters the turbine at 500°C and expands to 147kPa. If the powerplant is producing 5MW of energy find the following:
- Enthalpies at each point of the cycle 1,2,3,B (hint: you will have to interpolate horizontally for point 1 and interpolate for the f,g,fg values for point 2)
- Net work in kj/kg
- Mass flow rate of throttle steam used by the powerplant
- Heat added in the boiler
- Heat rejected in the condenser
- Cycle Thermal efficiency
