How to determine Coefficient of Viscosity
In study of Fluid Mechanics the viscosity is one of the major properties of fluid which is taken in consideration while analysing fluid motion. Viscosity- is an fluid property which tends to oppose or resist the motion of one layer of fluid over another layer. Viscosity in fluids is analogous to friction in solids. The first basic formula for it was given by Newton and the Law is known as Newton's law of viscosity . It tells that Shear Stress between adjacent fluid layers is directly proportional to the rate of change of velocity. τ = μ*( du/dy) where τ= Shear Stress; μ= Coefficient of Viscosity(dynamic) ; ( du/dy)= rate of change of velocity. Methods to determine Coefficient of Viscosity the following are the experimental methods to calculate coefficient of Viscosity 1. Capillary tube Method 2. Falling sphe
