We can take the example of a Pelton turbine for which the velocity triangle is drawn below:
The power is given to the runner,
\(P = \rho Q\left( {{V_{{w_1}}} + {V_{{w_2}}}} \right)u\)
Where, Vw1, Vw2 are the velocity of whirl at intel and exit respectively and u is the linear velocity of the rotor. All these parameters for the power calculation can be calculated using the velocity triangle for the given turbine.
