How to calculate torque on a shaft?

  1. Jun 13, 2012 #1
    I have designed and built a steam powered turbine that I am trying to get to run a compressor. In order to choose a compressor i've been trying to calculate how much torque my turbine is producing. The only figures i have are...

    RPM - found using a tachometer
    Combined weight of turbine blade and shaft
    Radius of turbine blade

    Is there anyway to calculate the torque using these figures?

    In a basic way you can take the power produced by the turbine and divide by the angular velocity of the rotor.
