A round-bottom triangular lined canal is to be laid at a slope of 1 in 1500, to carry a discharge of 25 m3/s. The side slopes of the canal cross-section are to be kept at 1.25H : 1V. If Manning’s roughness coefficient is 0.013, the flow depth (in meters) will be in the range of
A hypothetical multimedia filter, consisting of anthracite particles (specific gravity: 1.50), silica sand (specific gravity: 2.60), and ilmenite sand (specific gravity: 4.20), is to be designed for treating water/wastewater. After backwashing, the particles should settle forming three layers: coarse anthracite particles at the top of the bed, silica sand in the middle, and small ilmenite sand particles at the bottom of the bed.
Assume
(i) Slow discrete settling (Stoke’s law is applicable)
(ii) All particles are spherical
(iii) Diameter of silica sand particles is 0.20 mm
The CORRECT option fulfilling the diameter requirements for this filter media is
A 500 m long water distribution pipeline P with diameter 1.0 m, is used to convey 0.1 m3/s of flow. A new pipeline Q, with the same length and flow rate, is to replace P. The friction factors for P and Q are 0.04 and 0.01, respectively. The diameter of the pipeline Q (in meters) is ______________ (rounded off to 2 decimal places).
A flow velocity field $\vec{V} : \vec{V}(x, y)$ for a fluid is represented by
$\vec{V} = 3 \hat{i} + (5x) \hat{j}$
In the context of the fluid and the flow, which one of the following statements is CORRECT?
