Fluid friction is the drag between an object and particles of the medium. Air rushing against an airplane is an example of fluid friction.
Fluid friction:
It is the opposing force (friction) between an object and particles of the medium. In terms of air, fluid friction is know as Drag.
For example- friction between air and aeroplane.
Fluid friction depends upon two things,
1. The viscosity of the medium and
2. The speed of the moving object.
Formula for the air drag,
[tex]\bold {F_{D}=\frac{1}{2} \rho v^{2} C_{D} A}[/tex]
Where,
[tex]\bold {F_{D}}[/tex] = drag
[tex]\bold {\rho}[/tex] = density of fluid
v = speed of the object relative to the fluid
[tex]\bold {C_{D}}[/tex] = drag coefficient
A = cross sectional area
Therefore, air rushing against an airplane is an example of fluid friction.
