The venturi meter is to be installed in a schedule 40 4-in(ID=4.026 in) line to measure the flow of water. The maximum flow rate is expected to be 325 gal/min at 60°F. The 50-in manometer used to measure the differential pressure is to be filled with mercury, and water is to fill the leads above the mercury surfaces. The water temperature is to be 60°F throughout. What throat diameter should be specified for the venturi meter?

Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.
