A venturi tube is used to determine the airspeed at the throat/test section. During the test, a raise of 4.8 inches of water was recorded in the instrument. Determine the velocity of the at the (a) smallest and (b) largest section, when the ratio of the area between the largest and smallest section is 75:30. Assume incompressible flow and standard sea-level conditions. the answer should be v1 = 63.1962 ft/s and v2 = 157.9905 ft/s

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.
