False.

A venturimeter is a device used to measure the rate of flow, i.e the discharge through a pipe.

The working of venturimeter is based on the principle of Bernoulli’s equation.

It consists of three parts i.e, the converging cone, throat and diverging cone. The velocity of liquid at the throat is higher than that of inlet, also the pressure of liquid at the throat is lower than that of inlet and the velocity and pressure of liquid flowing through the divergent portion decreases.This difference in pressure is measured with the help of manometer and helps in determining rate of fluid flow or other discharge from the pipe line.

the discharge through a venturimeter is given by

discharge (Q) = (Cdx a1xa2x(2xgxh))/(a12 -a22)

Cd - coefficient of discharge

a1 -area of inlet

a2 - area at throat

h - venturimeter head
