Question

A jet of velocity V strikes a vane that moves to the right at
speed V_c, as in Fig. The vane has a turning angle θ.
Derive an expression for the power delivered to the vane by
the jet. For what vane speed is the power maximum?

Expert Solution

Step 1

Given data:

*The velocity of the jet is V.

*The velocity of the vane is V_c.

*The vane has a turning angle of θ.

The relative velocity of the jet and the van is V-Vc.

Thus, the force due to the flow of jet is given by:

Therefore, the power delivered to the vane by the jet is given by:

The maximum powers occur when the derivative of power with respect vane speed become zero, Thus,
