Friction due to fluids is called drag
WebOct 12, 2016 · Explanation: A stationary fluid exerts only normal pressure forces on the surface of a body immersed in it. A moving fluid, however, also exerts tangential shear forces on the surface because of the no-slip condition caused by viscous effects. Another in the direction normal to flow, which is the lift. WebViscosity is a measure of the "stickiness" or "resistance to deformation" of a fluid. It is due to the. internal frictional force that develops between different layers of fluids as they are forced to move relative. to each other. Viscosity is caused by the cohesive forces between the molecules in liquids, and by the.
