It is proposed that a 1,000-MW electric power plant be built with steam as the working fluid with the condenser to be cooled with river water. The maximum steam temperature is 550o C, and the pressure in the condenser is 10 kPa. The river, which is about 60 m wide and 8 m deep, has an average velocity of 10 m/min. Estimate the temperature rise of the river downstream from the power plant, in o C.
