Problem 627E

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 .

Step-by-Step Solution:
Step 1 of 3

 Anelastic (viscoelastic) material- a material in which the total strain developed has elastic and viscous components; Part of the total strain recovers similar to elastic strain. Some part, though, recovers over a period of time. Examples of viscoelastic materials include polymer melts and many polymers including silly putty. Typically, the term anelastic is used for metallic materials  Apparent viscosity- viscosity obtained by dividing shear stress by the corresponding value of the shear-strain rate for that stress  Bend test- application of a force to a bar that is supported on each end to determine the resistance of the material to a static or slowly applied load; typically used for brittle materials  Bingham plastic- a material with a mechanical
