Assertion (A): Reynolds number is the ratio of the inertia force to the viscous force.
Reason (R): Reynolds number is used to predict the flow regime of a fluid.

Explanation:
Reynolds number is a dimensionless quantity that is used to predict the flow regime of a fluid. It is defined as the ratio of the inertia force to the viscous force and is given by the equation:

Re = ρVD/μ

Where,
ρ = density of the fluid
V = velocity of the fluid
D = characteristic length of the flow (e.g. diameter of a pipe)
μ = dynamic viscosity of the fluid

The inertia force is the force that opposes any change in the motion of a fluid, while the viscous force is the force that opposes the relative motion between adjacent fluid layers. The ratio of these forces is important in determining the type of flow that will occur, such as laminar or turbulent flow.

Therefore, both statement A and statement R are individually true, but statement R is not the correct explanation of statement A. Reynolds number is used to predict the flow regime of a fluid, but this does not necessarily mean that it is the reason why the ratio of inertia force to viscous force is calculated.
