# Rankine cycle with reheat

- Water is used as working fluid;
- Pressure at the outlet of the low pressure turbine of 10 kPa;
- Pressure at the outlet of the high pressure turbine of 200 kPa;
- Pressure at the pump outlet of 1000 kPa;
- Temperatures after leaving the boiler of 250 °C;
- The pump has an isentropic efficiency of 90%;
- The turbines have an isentropic efficiency of 80%.
