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 m/s). Assume uniform, steady flow and assume a spherical particle with d = 2.0 mm
and neglect bed form roughness. Find the following by choosing the correct answer of the
following:
1- If the settling velocity vss = 1
m/s, the Reynolds number (Rep) is
equal to:
480.50
O 579.11
1686.34
O Non of them
2- If the settling velocity vss = 1
m/s, the drag coefficient (CD) is
equal to:
O 0.37
0.53
0.75
0.85
