A horizontal Venturi meter, which has a throat diameter of cm, is installed in a pipeline with a diameter of 30 cm. The pipe is running full of water (density 1000 kg/m) and the coefficient of discharge of the Venturi meter is 0.975. One pressure tapping is located at the throat and another in the pipeline upstream of the throat. The pressure difference measured between the two tappings is 74.5 mm of mercury. What is the actual flow rate (in 1/s)? (provide your answer with two decimal points)

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.
