WATER PUMPING BY USING NATURAL FLOW ENERGY OF STREAMS

Abstract

This research aimed to utilize the natural flow energy of streams through design of a mechanical system consists of a wheel with rectangular blades attached to asteel structure installed with two separated floating platforms on the stream, this wheel spins naturally by impulse of stream and transmits the rotational motion to a crank shaft linked with two reciprocating pumps deliver the water directly from the source up to storage or direct use according to need. Velocities, torques and power have been calculated based on the lowest available realistic assumptions with different directions and efficiencies, withsimplicity of design and durability for easier operation and maintenance, that is done by the selection of manufacturing materials that fulfill these requirements to maintainsystem continuity in water pumping for different activities as long as possible.
