How much inlet water can a hydraulic ram pump typically raise?

A hydraulic ram pump operates by utilizing the kinetic energy of a downward-flowing stream of water to lift a portion of that water to a higher elevation.12

Regarding the volume of water raised, approximately 15 percent of the water flowing through the inlet pipe can typically be lifted to a height of five times the vertical fall of the inlet pipe. The process relies on the conversion of kinetic energy into pressure energy, triggered by the sudden closing of a valve, which forces a small fraction of the total inlet water into an air chamber and up a discharge pipe.21
