Solved: An Ocean Thermal Energy Conversion (OTEC) power
Chapter 6, Problem 627E(choose chapter or problem)
An Ocean Thermal Energy Conversion (OTEC) power plant built in Hawaii in 1987 was designed to operate between the temperature limits of 868F at the ocean surface and 418F at a depth of 2100 ft. About 13,300 gpm of cold seawater was to be pumped from deep ocean through a 40-indiameter pipe to serve as the cooling medium or heat sink. If the cooling water experiences a temperature rise of 68F and the thermal efficiency is 2.5 percent, determine the amount of power generated. Take the density of seawater to be 64 lbm/ft3 .
