At high Reynolds number_________________?
Correct answer: A. Inertial forces control and viscous forces are unimportant
- A. Inertial forces control and viscous forces are unimportant
- B. Viscous forces predominate
- C. Inertial forces are unimportant and viscous forces control
- D. None of these
Explanation
A high Reynolds number means inertial forces are large relative to viscous forces, so flow behaviour is principally controlled by inertia and is often turbulent. Viscosity still exists, but its relative influence is small.
