Hi,
I am performing an unsteady simulation of an impeller and I would like to know the torque on all of the impeller blades. So far I am using a single moment monitor, with the axis defined as the impeller axis, which gives me the moment coefficient.

My question is as follows:
How do I get the real torque from the coefficient?

In the Fluent UG i found the formula
Moment_coef = Moment/(0.5*ro*v^2*A*L)

Where do I take these values from? Are those the reference values? Or should I get a monitor for each blade separately?

Thanks
