This return of part of thecooling water to the original supply is a feature addedsome time after the installation of the engines. Thetemperature of the well water is from 50 to 55 It was at first found that this was so low as tocause sweating in the air compressors due to the factthat the air drawn in from the room is at approximately72 deg. Fahr., and is moist from the steam-generatingequipment. Water formed in the air compress
