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.

Water flows in a channel with uniform curvature ?. The channel has height ℎ = 5 mm and width ? = 190 mm (normal to the drawing plane). The curved part of the channel has a length of ? = 100 mm in the ?-direction. You can assume that the channel height is very small compared to the curvature radius.Neglect effects of gravity. a) Assuming that the pressure is uniform on each of the channel walls, determine the pressure difference between the upper and lower wall that is needed if the required net force on the two walls is 2000 N pointing downward (in the negative ?-direction).Use a sign convention that a positive pressure difference or gradient means the pressure at the higher ?-position is higher. b) Your team agree that, from experience, the average velocity of the fluid is ?= 53 m/s. Assuming that the velocity is uniform across the channel, and neglecting gravitational effects, determine the curvature ?required to generate this force with this flow velocity.
