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
-
Power required to drive a centrifugal pump is __________ proportional to N3.
-
The force exerted (in newton) by a jetof water impinging normally on a fixed plate is (where w = Specific weight of water in N/m3, a = Cross-sectional area of jet in m2, and V = Velocity of jet in m/s)
-
The unit power developed by a turbine is (where P = Power developed by the turbine under a head of water (H))
-
A Pelton wheel develops 1750 kW under a head of 100 metres while running at 200 r.p.m. and discharging 2500 litres of water per second. The unit discharge of wheel is
-
Delivery head of a centrifugal pump is
