A venturi meter measures the flow of water in a 75mm diameter pipe. The difference between the throat and the entrance of the meter is measured by the U-tube contains mercury which is being in contact with the water. Calculate the diameter of the throat if the difference in level of mercury is 250mm when the quantity of water flowing in the pipe is 1.55m3/min. Assume coefficient of discharge is 0.97.

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.
