Two pipes of uniform section but different diameters carry water at the same flow rate. Water properties are the same in the two pipes. The Reynolds number, based on the pipe diameter
-
- if the same in the both pipes
- is large in then arrow pipe
- is smaller in the narrower pipe
- depends on the pipe material
Correct Option: B
| Reynolds number, Re = | |
| υ |
| Discharge, Q = AV = | d2V | |
| 4 |
| From above, = | |
| πd2 |
| ∴ Reynolds No. = | × | ||
| πd2 | 2 |
| Reynolds No. = | ....(1) | |
| πd |
| From (1), Re ∝ | |
| 2 |
Reynolds number is large in the Narrow pipe.
