Calculate Cp? need first to see if its possible to calculate that. Maybe from the torque.... from the Ct=T/(1/2*rho*v^2*A*R) and Cp=lambda*Ct ....???

The velocity can be calculated from

\begin{equation*}
v=r \times \omega_{}
\end{equation*}

Using r as the distance from the center to the mid of a blade: r=0.04m.

The angular velocity is 40rpm which corresponds to 4.1888rad/s.

Therefore, the expected velocity at the center of the blades is 0.1676m/s

We expect large vortices downstream the turbine?
