The ratio of inertial forces to viscous forces is called the ______________ number?
Correct answer: D. Reynold
- A. Weber
- B. Mach
- C. Froude
- D. Reynold
Explanation
The Reynolds number is the ratio of inertial forces to viscous forces, Re = ρvD/μ. It is used to distinguish laminar, transitional and turbulent flow.
