hydroelectric power

Physics

Electric power generated by a flow of water. A natural waterfall provides a source of energy, in the form of falling water, which can be used to drive a water turbine. This turbine can be coupled to a generator to provide electrical energy. Hydroelectric generators can be arranged to work in reverse so that during periods of low power demand current can be fed to the generator, which acts as a motor. This motor drives the turbine, which then acts as a pump. The pump then raises water to an elevated reservoir so that it can be used to provide extra power at peak-load periods.

Chemical Engineering

Electrical power generated from the flow of water through a water turbine connected to an electrical generator or alternator. The flow and pressure head of water is provided by a dam and channelled through a pipe to the water turbine below. The power generated is a product of the head, mass flow rate, and gravitational acceleration. Hydroelectric power stations produce electricity at peak times and can be used in reverse at other times to return water back into reservoirs for reuse.
