READ MOREA turbine is a device that harnesses the kinetic energy of some fluid - such as water, steam, air, or combustion gases - and turns this into the rotational motion of the device itself. Turbines are generally used in electrical generation, engines, and propulsion systems.Turbines are machines (specifically turbomachines) because turbines transmit
READ MOREWater turbines. Water wheels, which date back over 2000 years to the time of the ancient Greeks, were the original water turbines. Photo: A water wheel is an ancient form of turbine. In this overshot wheel, the water is chaneled over the top by the wooden boards and pushes the wheel round as it flows down.

READ MOREThere are two main types of hydropower turbines: reaction and impulse. The type of hydropower turbine selected for a project is based on the height of standing water—referred to as "head"—and the flow, or volume of water over time, at the site. Other deciding factors include how deep the turbine must be set, turbine efficiency, and cost.

READ MOREReaction turbines are turbines that use the pressure as well as the velocity of the moving water to rotate. Reaction turbines are placed in the water stream where the water enters the casing tangentially. Impulse Turbine and Reaction Turbine. Impulse turbines are most efficient for use in cases where the flow is low, and the inlet pressure is high.
READ MOREA wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.
