A venturi meter is an instrument which is to calculate the liquid flow in tubes.

. P1 Pressure at the inlet in Nm2. This meter is works on the principle of Bernoullis equation. It is through these changes in the fluid flow that the flow rate can be deduced.

A1 Inlet area in m2. If D2 D1 you get the square root of a negative number but. D1 Diameter of Inlet.

The volumetric flow rate through the pipe is Q 5 10-3 m 3 s. The discharge coefficient C is a constant value for given venturi dimensions. It is a function of the inertia force ρ u L and the viscous.

The venturi meter device measures the flow rate or velocity of a fluid through a pipe. Venturi flow meters like all other types of differential pressure flow meters function on the principles of the. The several notations use in this derivation.
