I wanted to calculate the amount of thrust generated from the engines. I am using the blade 180 cfx model.

After some research I have found a way to calculate the thrust using:
T = ( pi D^2 rho P^2)/2 where P is the Power multiplier and can be calculated using: P= prop constant * (rpm/100)^power factor
I am unable to find the values for the Prop constant and the power factor. Is there a way I can get this information? Or an alternative way to calculate the thrust generated?
