What is venturimeter in detail.

$\huge\mathfrak\red{Answer}$

A venturimeter is a device used to measure the fluid flow through pipes. This flow measurement device is based on the principle of Bernoulli’s equation. Inside the pipe , pressure difference is created by reducing the cross-sectional area of the flow passage.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. As the main inlet area is more as compared to throat , velocity of fluid at throat increases therefore pressure decreases . By this, a pressure difference is created between the inlet and the throat of the venturimeter. Hence, by reducing the cross-sectional area of the flow passage, a pressure difference is created and we measure that difference in pressure by using Bernoulli equation and discharge formula .
