Question:

A fluid jet of diameter D1 enters a cascade of moving blades at absolute velocity V1 and angle β1, and it leaves at absolute velocity V1 and angle β2, as in Fig. P3.78. The blades move at velocity u. Derive a formula for the power P delivered to the blades as a function of these parameters.
