Mechanical Properties Of Fluid

Retarding force acting on a ball falling into a viscous fluid where radius of ball, velocity of ball, and coefficient of viscosity. and Or in words, retarding force is directly proportional to both R and

Fluid resistance is given by
When two capillary tubes of same size are joined in parallel, then equivalent fluid resistance is


Equivalent resistance becomes times so, rate of flow will be

The pressure on the rear side would be more due to fictitious force (acting in the opposite direction of acceleration ) on the rear face. Consequently, the pressure in the front side would be lowered.
