A proposal is to build a 1000-MW electric power plant with steam as the working fluid. The condensers are to be cooled with river water (see Fig. P5.61). The maximum steam temperature is 550◦C, and the pressure in the condensers will be 10 kPa. Estimate the temperature rise of the river downstream from the power plant.
