Although considerable formulae have been given which represent the relation between suction performance and inlet flow condition of centrifugal pump impeller, there exists some lack of consideration of the flow condition at discharge flow rates other than normal. In this report, indicative values of suction condition and suction performance of centrifugal pumps which are used at present in diverse signs and names are reviewed and discussed systematically, and a concise formula which represents the relation between suction performance and inlet flow condition is introduced under consideration of the wide range of discharge flow-rate. Then, the law of similarity for suction performance is formulated under the assumption that the flow condition near the impeller inlet keeps the geometrical similarity when the pump speed is changed. Besides, the law of similarity for suction performance in such a cavitation condition as causes the pump head to drop is considered.
