The power developed by a turbine is (where H = Head of water under which the turbine is working)
If V1 and V2 are the velocities of water at inlet and outlet of the draft tube respectively, then the efficiency of a draft tube is
A jet of water enters and leaves a fixed curved vane tangentially. The force of jet along perpendicular to the vane is zero.
In a mixed flow centrifugal pump, the flow through the impeller is a combination of radial and axial flows.
A Pelton wheel is
