Practice Questions

Coefficient of discharge is the ratio of actual discharge to the theoretical discharge. For venturimeter, the value of Cd lies between 0.95 to 0.98. Similarly, for orifice meter, it is 0.62 to 0.65 and for nozzle meter, it is 0.93 to 0.98.

An orifice is a small opening made on the bottom or sidewall of a tank for fluid to flow. The contraction of area for flow depends on the orifice's shape, size, and head. Notch or weir is a structure to measure channel section discharge.

An orifice meter is a cylindrical tube with a plate containing a thin hole in the middle. The fluid flows faster through the hole to maintain the flow rate.

A pipe has contra, throat and divergent portion

A pipe has a circular plate with a hole inside it

A large tank with a small hole at one of its ends

A pitot tube is used to measure the velocity of flow in a pipe or channel. It consists of a glass tube bent at a right angle and operates on the principle of kinetic energy conversion to pressure energy.

It is made up of a tapered tube and a float inside it

It consists of a thin metal sheet, having in it a square edged, a sharp edge or round edged circular hole

It consists of a glass tube bent at right angles

It consists of a short converging part, throat and diverging
