Abstract
A system is described for testing a pump or a turbine impeller under transient operating conditions in a fluid flow. The system provides simultaneously, as a function of time, user defined impeller speeds, fluid flow rate and rise in fluid pressure so as to simulate real conditions. This information can be used to analyze the performance of existing impellers or for designating new impellers.
