The described calculation procedure originated from the necessity of determining waterjet pump performance requirements for waterjet propelled ( sea ) vessels. The waterjet pump sizing procedure is basically in two parts. The purpose of the first part is to determine the requirements of flow rate and head required on any pump to produce the necessary thrust to achieve design speed. Secondly, where the pump requirements are known, studies to determine pump rpm, cavitation limitation, impeller diameter, case volume and wet weight can be made to estimate some detailed aspects of various pump types which might be applied. A computer program was developed from this procedure which streamlines studying variations in design. The procedures and the computer program can also be used in evaluating waterjet systems presented in studies and proposals. ( Author )
