Difference between an Impulse Turbine and Reaction Turbine

Points : Difference between an Impulse Turbine and Reaction Turbine Following are the few points of difference between a reaction turbine aid an impulse turbine:

Difference between an Impulse Turbine and Reaction Turbine
	Impulse Turbine	Reaction Turbine
1.	The entire available energy of the water is first converted into kinetic energy.	The available energy, of the water, is not converted from one form into another.
2.	The water flows through the nozzles and impinges on the buckets, which are fixed to the outer periphery of the wheel.	The water is guided by the guide blades to flow over the moving varies.
3.	The water impinges on the buckets, with kinetic energy.	The water glides, over the moving vanes, with pressures energy.
4.	The pressure of the flowing wallet remains unchanged, and is equal to the atmospheric pressure.	The pressure of the flowing water is reduced after gliding over the vanes.
5.	It is not essential that the wheel should run full. Moreover there should be free access of air between the vanes and the wheel.	It is essential that the wheel should always run full, and kept full of water.
6.	The water may be admitted over a part of the circumference or over the whole circumference of the wheel.	The water must be admitted over the whole circumference of the wheel.
7.	It is possible to regulate the flow without loss.	It is not possible to regulate he flow without loss.
8.	The work is done only by the change in the kinetic energy of the jet.	The work is done partly by the change in the velocity head, but almost entirely by the change in pressure head.
