At very low Re, viscous effects pre-dominate and the contribution of inertial forces can be ignored. A clear example of the changing contribution of viscous and inertial or momentum effects and the resulting changes in the flow pattern is given in Figure 2.
The formula for Reynolds Number is as given below. In the formula given above,. L is the characteristic linear dimension. V is the kinematic velocity of the given fluid.
