In this article we shall study to solve problems on calculation of viscous force, coefficient of viscosity, and velocity gradient. Example 01: Calculate the horizontal force required to move a metal plate of area 2 x 10-2 m2 with a velocity of 4.5 x 10-2 m s-1 when it rests on a layer of oil […]
Some liquids like water Kerosene flow very easily while some liquids like honey, glycerine do not flow easily. The property by virtue of which a liquid or a fluid opposes the relative motion between two adjacent layers is called viscosity. The force which opposes the relative motion between two adjacent layers in a fluid is […]
