Power required to run a turbine?

[crazybuoy]

I want to find out the power required to run the turbine and the pressure of steam required to maintain the power requirement of turbine. Please tell me about any formula or method to resolve this issue.

I think a good place to start would be to determine the torque required to turn the turbine at the speed you require, i.e the turning force.

Unfortunately it's not going to be as simple as applying a few equations. The pressure of steam required will depend on the pipe size feeding to the turbine, its length, temperature and also how much steam is lost at the pipe-turbine interface.
