I have tried to study Colebrook equation for the relation of open channel slurry flow velocity and solid concentration at certain effective linear wall roughness, hydraulic radius and slope.
From the equation
(6-6) in Slurry Systems Handbook
It can be derived for velocity as
Replace V in...
I have done a study of Darcy friction factor formula to find the relation between open channel slope and channel wall roughness or solids concentration.

The equation for slurry dynamic viscosity calculation is also checked with solid concentration by volume where liquid dynamic viscosity μL = 0.00167 Pa•s

Hi Mech85,
The calculation is done with the corrected equation.
(by Dominguz et al. 1996)
(from Slurry System Handbook)
Where:
μm slurry absolute viscosity (Pa•s)
μL carrier absolute viscosity (Pa•s)
ρm slurry density (kg/m3)
Below are charts of deposition velocity VD (m/s) related...
Thanks a lot to IRstuff for the book you recommended. It is a great reference.
Thanks Mech85 for the clarification, I'll verify my calculation with your correction and report the result.

An equation below for deposition velocity estimation is introduced in Slurry Systems Handbook. This equation was published by Dominguez et al (1996).
(6-52)
where:
g - gravity acceleration
RH - hydraulic radius
ρS - solids density
ρm - slurry density
d85 - solid particle size...
