Abstract : Procedures are described for determining the losses in a liquid annular ring type of gas compressor. The development of a new type of partial bearing is discussed as well as the calibration of a testing motor and the construction and tests of a prototype. Data from experimental runs indicated that this low-cost, smooth-running, medium-speed (3000 rpm) compressor in a 3-hp size will develop 62% isothermal efficiency and deliver 53 cu ft/min of oil-free air at 4 psi.
