I am trying to find the maximum theoretical rotational power of a turbine from the following quantities: $\omega$, $r$, $\gamma$, $I$, and $t$.
This is in an experimental setting, not an assignment, so I am not sure if I am missing any necessary quantities.
My problem: I know that $P=\tau\omega$, but I am having trouble finding torque in this scenario. More specifically, I have $r$, but I do not know how to go about finding $F$. I have $\gamma$, which is the angle between the turbine blade and the water inflow vector. I would use this once I find $F$. The only forces on the rotating bodies are water inflow and centripetal force. I did some research and found that centripetal force would be negligible in this case as the blades are rigid bodies.
I have velocity and mass flow rate, although I cannot find a formula to find impact force on a water turbine blade, $F$.
Any guidance as to how to find $F$ would be greatly appreciated.
I know that once I find the power of a single blade, I can calculate the rotational power of the turbine.
