Transcribed Image Text:. Assuming the criterion for suspended load transport is u-/v> 0.40 and for bed load
transport is u-/v> 0.10, a rectangular channel (B = 7 m, S, = 0.0005, n = 0.015, v= 1.186 x
10 m²/s). Assume uniform, steady flow and assume a spherical particle with dso = 2.0 mm
and neglect bed form roughness. Find the following by choosing the correct answer of the

Expert Solution
Step 1
Objective: To determine the settling velocity.
Given:
Kinematic viscosity () = 1.18610-4 m2/s
Diameter of the particles (dp) = d50 = 2 mm
Drag coefficient (Cd) = 0.85
For laminar flow, the settling velocity can be given as:
here,
SG: specific gravity of the particles, typically adopted to be 2.65.
