The Reynolds number for an ideal fluid flow is _________________?
Correct answer: D. ∞
- A. 4
- B. 2100-4000
- C. 4000
- D. ∞
Explanation
The Reynolds number is Re = ρvD/μ, and an ideal fluid has zero viscosity, μ = 0. For nonzero density, velocity and diameter, division by zero makes the Reynolds number theoretically infinite.
