The report describes some measurements made of film entrance losses for a circular, externally pressurized, gas bearing under subsonic flow conditions. The nature of the flow in the entrance region was studied by means of pressure profile measurements. Measurements were made of the recovery of pressure downstream of an orifice discharging into the bearing feeding hole and of the influence of this orifice on film entrance pressure loss. The significance of these various phenomena on bearing performance was demonstrated by an illustrative calculation for a typical bearing.
