A venturi meter is a device used to measure the flow rate of a fluid. The fluid flows through a constricted area, which causes the fluid to accelerate. The fluid then flows through a diffuser, which slows the fluid down. The difference in the fluid’s speed before and after the constriction is used to calculate the flow rate.

The fluid’s speed is proportional to the square root of the pressure difference across the constriction. This relationship is known as the Bernoulli equation. The venturi meter uses this relationship to calculate the flow rate.

The venturi meter is named after Giovanni Battista Venturi, who first described the Bernoulli equation in 1738.

Q: What does Z represent in fluid mechanics?

A: In fluid mechanics, Z represents the height of a fluid above a reference point.

Q: What is Z in pipe flow?

A: Z is the head loss in pipe flow.

Q: What does Z stand for in Bernoulli’s equation?

A: There is no definitive answer to this question, as the letter Z is typically used to denote the fluid height in Bernoulli’s equation, which is a simplified form of the Bernoulli principle. However, some sources suggest that the letter Z may represent the distance between two points in a fluid flow, or the vertical coordinate in a three-dimensional fluid flow.

Q: What is Venturi meter coefficient?

A: The Venturi meter coefficient is a measure of how well the Venturi meter is able to accurately measure the flow of fluid through a pipe.
