Mathematics · Fluid Mechanics - Pipe Flow
In a 400 mm diameter pipe carrying turbulent flow, the center-line velocity is 8 m/s, and the velocity at a distance of 60 mm from the pipe wall is 1.137 m/s. Calculate the shear friction velocity.
- 1uf = 510.0 m/s
- 2uf = 5.20 m/s
- 3uf = 2.28 m/s✓
- 4uf = 7.00 m/s
Correct answer
uf = 2.28 m/s
