The hydraulic mean depth of a circular section running full is _______...
The hydraulic mean depth, R = Area of cross section / Wetted perimeter
= ((22/7) *D2/4) / (22/7) *D
= D/4.
= ((22/7) *D2/4) / (22/7) *D
= D/4.

The hydraulic mean depth of a circular section running full is _______...
Hydraulic mean depth of a circular section
- The hydraulic mean depth (Dm) is defined as the ratio of the cross-sectional area of flow (A) to the wetted perimeter (P) of the channel.
- For a circular section running full, the wetted perimeter is equal to the circumference of the circle (C), which is πD, where D is the diameter of the circle.
- Therefore, the hydraulic mean depth of a circular section running full can be calculated as follows:
Dm = A/P = πD^2/πD = D/4
- Hence, the correct answer is option D, i.e., D/4.
