The flow in a pipe or channel is said to be non-uniform when

The product of mass and acceleration of flowing liquid is called

The property by virtue of which a liquid opposes relative motion between its different layers is called

The ratio of quantity of liquid discharged per second from the pump to the quantity of liquid passing per second through the impeller is known as

The breast water wheels are those in which the wheel runs partly by the weight of water and partly by the impulse of water.

The maximum efficiency of jet propulsion of a ship with inlet orifices at right angles to the direction of motion of ship, is

The capacity of a hydraulic accumulator is generally specified as the maximum amount of energy stored.

In an impulse turbine, the jet of water impinges on the bucket with a low velocity and after flowing over the vanes, leaves with a high velocity.

Manometric head, in case of a centrifugal pump, is equal to

In a reaction turbine, the pressure head of water, while flowing over the vanes, is converted into kinetic head before leaving the wheel.

For centrifugal pump impeller, the maximum value of the vane exit angle is

The unit of dynamic viscosity in S.I. units is

In the casing of a centrifugal pump, the kinetic energy of the water is converted into pressure energy before the water leaves the casing.

The principle of jet propulsion is used in driving the ships and aeroplanes.

A hydraulic coupling belongs to the category of

When the speed of the pump increases, its net positive suction head (NPSH) requirement decreases.

A centrifugal pump will start delivering liquid only when the pressure rise in the impeller is equal to the

Discharge (Q) of a centrifugal pump is given by (where D = Diameter of impeller at inlet, b = Width of impeller at inlet, and Vf = Velocity of flow at inlet)
