This paper presents a method of directly calculating an optimum jet pump geometry for a set of specified conditions. It reviews jet pump theory to the extent necessary for explaining the sizing technique. The method uses a design performance curve which is a composite of the family of performance curves for the pump. An exact nozzle area is calculated and an area ratio selected, based on the design curve. This data is then used to select an off the shelf geometry from a manufacturer. The calculation sequence is presented along with an example set of calculations which follow that sequence.
