An error of 1% in measuring head over the apex of the notch (H) will produce an error of __________ in discharge over a triangular notch.

A vertical wall is subjected to a pressure due to one kind of liquid, on one of its sides. The total pressure on the wall per unit length is (where w = Specific weight of liquid, and H = Height of liquid)

A weir is said to be broad crested weir, if the width of the crest of the weir is __________ half the height of water above the weir crest.

The discharge over a right angled notch is (where H = Height of liquid above the apex of notch)

The diameter of the nozzle (d) for maximum transmission of power is given by (where D = Diameter of pipe, f = Darcy 's coefficient of friction for pipe, and l = Length of pipe )

The kinematic viscosity is the

In one dimensional flow, the flow

In a depressed nappe
