If Reynolds number is greater than 1, then the

ANS:B - inertia force is larger than the viscous force.

If the Reynolds number is greater than 1, then the inertia force is larger than the viscous force. The Reynolds number (Re) is a dimensionless quantity used to predict flow patterns in different fluid flow situations. It is defined as the ratio of inertial forces to viscous forces within a fluid flow, and it is given by: Re=Viscous forces/Inertial forces​=ρ⋅V⋅L​/μ Where:

• ρ is the density of the fluid,
• V is the velocity of the fluid,
• L is a characteristic length (such as the diameter of a pipe),
• μ is the dynamic viscosity of the fluid.

When the Reynolds number is greater than 1, it indicates that inertial forces dominate over viscous forces. In other words, the flow is more influenced by the fluid's momentum (inertia) than by its viscosity. Therefore, the correct statement is: inertia force is larger than the viscous force.
