An Ocean Thermal Energy Conversion (OTEC) power plant built in Hawaii in 1987 was de-
signed 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 gallons per minute (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 eciency is 2.5%,
determine the amount of power generated. The density of seawater is approximately 64 lbm/ft3.
