Experiment No. 16 Viscosity Aim: To verify Stoke's law and hence to determine the coefficient of viscosity of a highly viscous liquid. ... In actual practice the experiment is performed in a liquid column of finite depth H contained in a cylinder of inner radius R. To take into account the effect of the finite depth and radius of the liquid
PDF Experiment 6: Viscosity (Stoke's Law)
Viscosity is a property of uids (liquids and gases) which determines how much resistance is experienced by an object trying to move through the uid. In this experiment we will use Stoke's Law and the concept of terminal velocity to determine the viscosity of glycerin. Objective Use Stoke's Law to derive an equation relating the viscosity of a
PDF MEASUREMENT OF VISCOSITY BY THE STOKES METHOD
symbol for dynamic viscosity used by mechanical and chemical engineers — as well as fluid dynamicists — is the Greek letter mu (µ). Kinematic viscosity is the dynamic viscosity divided by the density (units m 2/s). Accepted values of the dynamic viscosity of some selected liquids and gases for temperature of 20ºC and pressure 1.10 5 Pa.
