Question

6-26E An Ocean Thermal Energy Conversion (OTEC) power plant built in Hawaii in 1987 was designed to operate between the temperature limits of 86"F at the ocean surface and 41"F at a depth of 2100 ft. About 13,300 gpm of cold seawater was to be pumped from deep ocean through a 40-in-diameter pipe to serve as the cooling medium or heat sink. If the cooling water experiences a temperature rise of 6"F and the thermal efficiency is 2.5 percent, determine the amount of power generated. Take the density of seawater to be 64 Ibm/ft.
