The critical depth for a channel is given by (where q = Unit discharge (discharge per unit width) through the channel)

The liquid used in manometers should have

The viscosity of a liquid __________ its rate of flow through a hole in a vessel.

The formula for discharge over a sharp-crested weir and Ogee weir is same as that of a rectangular weir

When a body is placed over a liquid, it will float if

The Cippoletti weir is a __________ weir.

Gauge pressure at a point is equal to the absolute pressure __________ the atmospheric pressure.

The pressure of a liquid measured with the help of a piezometer tube is

The hydraulic gradient line lies over the centre line of the pipe by an amount equal to the

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

The ratio of the inertia force to the viscous force is called

A flow whose streamline is represented by a straight line, is called __________ dimensional flow.

The velocity at which the flow changes from laminar flow to turbulent flow is called

The discharge through a channel of trapezoidal section is maximum when

The vacuum pressure is always the negative gauge pressure.

The value of coefficient of discharge is __________ the value of coefficient of velocity.

When the water level on the downstream side of a weir is above the top surface of a weir, the weir is known as

Reynold's number is the ratio of the inertia force to the

A uniform body 3 m long, 2 m wide and 1 m deep floats in water. If the depth of immersion is 0.6 m, then the weight of the body is
