Hogan, William T. | Liepins, A. A. | Reed, F. Everett
A procedure for predicting the temperature of a thermally loaded captive pond is presented. Using this information, the cooling pond is shown in a special case to have an economic advantage over a cooling tower and to be not much more expensive than a natural body (stream or ocean) of water. This, with the ecological and recreational assets of a captive cooling pond, would seem to encourage their expanded use with large thermo-electric power plants.
