what is fluid friction ?
Asked by shuchi.saumya | 16th Oct, 2010, 12:00: AM
Friction is the force resisting the relative motion of solid surfaces, fluid layers, or material elements sliding against each other. It may be thought of as the opposite of "slipperiness".
Fluid friction describes the friction between layers within a viscous fluids that are moving relative to each other.
In fluid dynamics, drag (sometimes called air resistance or fluid resistance) refers to forces that oppose the relative motion of an object through a fluid (a liquid or gas). Drag forces act in a direction opposite to the oncoming flow velocity.
We hope that above clarifies your doubt.
