How to decide pressure for turbine?

[ankit.4aug]

I want to know ..how to know how much pressure is needed for electricity turbine generator??

? There are many different kinds and sizes of generators. Even with a given generator, the force needed will depend on how fast you want to generate the electricity. Any amount of pressure on the blades of a generator will produce some electricity.

but there must be some mimimum pressure to rotate the turbine...i want to know how to calculate that for a given turbine??

 

[HallsofIvy]

Well, that would again depend upon a large number of things- area of vanes, how the vanes are tilted to the vertical, friction at the pivot, ...

i am getting around 200 kpa..could you roughly tell me is that enough..if yes then how big would be the turbine??
