AI Thread Summary
Determining the required pressure for a turbine generator involves several factors, including the generator's type and size, desired electricity generation speed, and the turbine's design specifics like vane area and tilt. A minimum pressure is necessary to initiate turbine rotation, and calculations will vary based on these parameters. The discussion mentions achieving around 200 kPa, questioning if this pressure is sufficient for turbine operation. The conversation also humorously touches on the complexities of measuring turbine dimensions, indicating that precise answers depend on various conditions. Overall, understanding the relationship between pressure and turbine design is crucial for effective electricity generation.

I want to know ..how to know how much pressure is needed for electricity turbine generator??
 
Physics news on Phys.org
? 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??
 
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??
 
How long is a piece of string?
 
1 metre...
 
I'm getting 1.456 meters. Could someone tell me how heavy is the string?
