This Standard is designed to cover the determination of the performance and efficiency of pumps when handling water at temperatures up to 85 degrees F., provided that proper precautions are taken to damp down pulsations of flow and pressure at the measuring devices. The formulae are based on the assumption that the water being handled is of a standard density of 62.3 lb. per cu. ft. (i.e., water at 62 degrees F.).
