A preliminary study was made of the flow phenomena within the rotating passages of a 48-inch radial-inlet impeller at low tip speeds. Total and static pressures were measured within the impeller passages, at tip speeds of 500 and 700 feet per second, by using a suitable pressure-transfer device to transmit the pressures from the rotating passages to the stationary measuring station.
