11 Facts About Water turbine

Water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work.

Water turbine wheels have been used for hundreds of years for industrial power.

In 1844, Uriah A Boyden developed an outward flow turbine that improved on the performance of the Fourneyron turbine.

The Francis turbine is called a radial flow turbine, since water flows from the outer circumference towards the centre of runner.

Precise shape of water turbine blades is a function of the supply pressure of water, and the type of impeller selected.

Since the turbine is spinning, the force acts through a distance and the diverted water flow is left with diminished energy.

An impulse Water turbine is one in which the pressure of the fluid flowing over the rotor blades is constant and all the work output is due to the change in kinetic energy of the fluid.

Specific speed of a Water turbine characterizes the Water turbine's shape in a way that is not related to its size.

The specific speed is the speed with which the Water turbine turns for a particular discharge Q, with unit head and thereby is able to produce unit power.

Flow through the Water turbine is controlled either by a large valve or by wicket gates arranged around the outside of the Water turbine runner.

The Water turbine will be designed to survive the mechanical forces of this speed.
