- A venturi meter is essentially a short pipe consisting of two conical parts with a short portion of uniform cross-section in between.
- This short portion has the minimum area and is known as the throat.
- The two conical portions have the same base diameter, but one has a shorter length with a larger cone angle while the other has a larger length with a smaller cone angle.
- The venturi meter is always used in a way that the upstream part of the flow takes place through the short conical portion while the downstream part of the flow is through the long one.
- The value of Cd for a venturi meter usually lies between 0.95 to 0.98.
- A venturi meter is a device used for measuring the rate of flow of a fluid flowing through a pipe.
- The size of the venturi meter is specified by its pipe diameter as well as throat diameter.
- It has a small convergent portion to ensure rapid conversion and a larger divergent portion to ensure gradual passage in the direction of flow to avoid the energy loss.
- The angle of convergence is 20°. The angle of divergence is 6° to 7°.
