A power plant operates in an idealized Rankine cycle, using water as the working fluid (Figure 3). The steam at the exit of the boiler has a pressure of 6 MPa and temperature of 600 °C (point 1). The water at the exit of the condenser has a pressure of 15 kPa (point 3). The condenser employs a nearby river as the cooling source, which can be regarded to have a constant temperature of 25 °C.
