What powers a hydraulic ram used for elevating water?

A hydraulic ram operates using the principle of water hammer, specifically taking advantage of the kinetic energy of flowing water to elevate a portion of that water to a higher elevation. The mechanism is designed to utilize a flow of water, typically from a stream or a well, which is directed into the ram. As water flows into the hydraulic ram, it accelerates and builds pressure upon encountering a sudden closure of a valve. This pressure then forces a small volume of water upward against gravity through a delivery pipe, effectively pumping it to a higher location.

This process does not require any external power source such as wind, electricity, or heat. Instead, it relies solely on the energy created by the movement of water itself, making it an efficient and sustainable method for elevating water in agricultural or rural settings.
