In this report, the authers try to investigate the relation between the cavitation aspect in a centrifugal pump impeller and the fall of the pump head due to cavitation, by the method of dividing the decrease of the pump head due to cavitation into the decrease of the work-done of the impeller per unit weight for-rate of water and the increase of the head loss in the pump. First, the relations between the increase and decrease of the work-done of the impeller per unit weight flow-rate of waler and the region where the cavitation takes place are discussed and verified by the results of observation of the cavitation aspect. Next, the relations between the additional head loss due to cavitation and the cavitation aspect in the impeller are investigated. Further, the flow-rate where the reverse-flow occurs at the inlet of the impeller is investigated, using the nature that the additional head loss changes abruptly at this flow-rate.
