Discussion Overview

The discussion revolves around determining the necessary pressure for a turbine generator to produce electricity. Participants explore various factors influencing this pressure requirement, including turbine design and operational conditions.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • Some participants note that the required pressure for a turbine generator varies based on the type and size of the generator, as well as the desired electricity generation speed.
  • Others argue that there is a minimum pressure needed to initiate turbine rotation, but the calculation of this pressure depends on multiple factors such as the area of the vanes and their tilt.
  • One participant mentions a specific pressure value of around 200 kPa and seeks clarification on whether this is sufficient and what size turbine would be appropriate.
  • A later reply humorously questions the relevance of the inquiry by comparing it to an ambiguous question about the length of a piece of string.

Areas of Agreement / Disagreement

Participants express differing views on the factors affecting turbine pressure requirements, and there is no consensus on a specific pressure value or calculation method.

Contextual Notes

The discussion highlights the complexity of calculating turbine pressure, with dependencies on design specifics and operational conditions remaining unresolved.

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?
