GENERAL KNOWLEDGE

Detailed explanation-1: -The Venturi tube or venturimeter is an instrument for measuring with accuracy the flow rate of fluids in pipes.

Detailed explanation-2: -A venturi meter is used to measure the flow speed of a fluid in a pipe. The meter is connected between two sections of the pipe; the cross-sectional area A of the entrance and exit of the meter matches the pipes cross-sectional area.

Detailed explanation-3: -A venturi works by measuring the difference in pressure at two different locations. The pressure difference is created by reducing the diameter of the pipe causing the fluid to flow faster. The fast moving fluid has a lower pressure than the slower fluid in the larger section of the venturi.
