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.

The front and side views of a centrifugal impeller are shown in the figure below. All symbols have their usual meanings. The outer radius of the impeller is r2 = 0.4 m and the blade height at the impeller outlet b2₂ = 0.03 m. The volume flow rate of water (density = 1000 kg/m³) through the impeller is 0.2 m³/s. The outlet blade angle 8₂ = 50 degrees and the impeller rotational speed w=1600 rpm. Assume negligible losses, and the design conditions of whirl-free and shock-free entry. The impeller torque is B₂F N-m. Front View 12 b2 |+| Side View
