Statement-1: For reynold number `R_(e)gt2000` the flow of fluid is turbulent.
Statement-2: Inertial forces are dominant compared to the viscous forces at such high reynold numbers.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion
B. If both assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false

Answer

A

Explanation

Reynold's number represents the ratio of the incrtial force is refer as inertia (mass of moving fluid) per unit area to the viscous force per unit area. When `R_(e)gt2000`, the flow is often turbulent in that case internal force dominate viscous force.
