A power plant uses heat from a nuclear reaction to produce work. Water flows through a pump, boiler, turbine, condenser, and back to the pump in a continuous cycle. The boiler pressure is and the condenser pressure is . The pump and turbine have isentropic efficiencies of and respectively. The turbine inlet temperature is , and the condenser outlet is saturated liquid.
What are
- The quality at the turbine outlet
- The temperature rise across the pump due to irreversibilities
- The work input to the pump, per kg of steam
- The heat input to the boiler, per kg of steam
- The work output from the turbine, per kg of steam
- The heat rejection from the condenser, per kg of steam
- The thermal efficiency
- The lowest possible temperature of the thermal reservoir that this heat engine accepts heat from
- The highest possible temperature of the thermal reservoir that this heat engine rejects heat to
- The maximum possible thermal efficiency for a device operating between reservoirs at the above temperatures
Note: This question will take a long time, and has been assigned a very high weight to account for this fact. It may be more convenient to calculate these results in a different order
