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 .
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
