What is the name of the instrument used for measuring the speed and rate of flow of a fluid that is flowing in a pipe?

Show answer & explanation

Correct answer: A

Explanation

The correct asnwer is option 1 i.e. Venturimeter.

  • Venturimeter is a device used for measuring the speed of a fluid within a pipe.
  • The venturimeter theory works on the Bernoulli equation such that the velocity increases as the pressure decreases.
  • This theory also states that when the cross sectional area of the flow decreases, a pressure difference between the different regions of the flow is created, and it helps to measure the difference under pressure.
