WebFeb 15, 2024 · Aim: To determine the relative viscosity of given liquid using Ostwald’s viscometer Procedure Part-II : Determination of viscosity 1) Clean the viscometer with chromic acid solution and then with distilled water. Rinse with water and ether and then dry. 2) Attach the viscometer to the burette stand in exactly vertical position. WebProcedure: Prepare bentonite magma (5%w/v), methylcellulose (2%w/v) and mineral oil. They show a Non-Newtonian rheological profile. Measure the viscosity of these liquids using a Brookfield viscometer and observe the thixotropy phenomenon. Place the spindle with the correct number listed in the data sheet in each liquid and rotate the spindle ...

WebAbstract. Viscosity is a fundamental characteristic property of all liquids. When a liquid flows, it has an internal resistance to flow. Viscosity is a measure of this resistance to flow or shear. Viscosity can also be termed as a drag force and is a measure of the frictional properties of the fluid. Viscosity is a function of temperature and ... WebThis video explains about the determination of viscosity co-efficient of a liquid using ostwald’s viscometer. Webwhere the coefficient of viscosity of the solution, η 1, can be computed by multiplying the coefficient of viscosity of water, η 2 = 8.95 mP to ρ 1 t 1 ρ 2 t 2. The pressure drop that is observed when a liquid flows through a pipe is a direct consequence of viscosity.
