32. Velocity profile for turbulent flow in smooth circular pipes may be empirically expressed as V(r) = Vmax(1 - ŋ)". The value of the exponent m depends on the flow condition and varies from 1/6 to 1/10, with 1/7 being used for wide ranges of turbulent flow. Find the ratio of the average to the maximum velosity in the flow field V /Vmax =f (m). [Ans.: V /V max = 2 /[(m +1)(m +2) ]. %3D

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.
