Water enters a circular pipe of length L = 5.0 m and diameter D = 0.20 m with Reynolds number ReD = 500. The velocity profile at the inlet of the pipe is uniform while it is parabolic at the exit. The Reynolds number at the exit of the pipe is_____
-
- 577
- 500
- 520
- 5.00
Correct Option: B
Since discharge is not changing average velocity in constant dia pipe will not change
| Re = | ||
| μ |
Reynold’s no. will not change
Re at exit = 500
