In this paper the authors studied on laminar flow of paper slurry in connection with the hydraulic transportation of wastes.
Applying the thin layer model of water near the inner wall of pipe in laminar flow, the relation between coefficient of friction λ_p and moddyfied Reynolds number R_ep was investigated theoretically and experimentally.
As the results the following relations were ascertained, _??_
and also, the following values were obtained,
_??_
where, D=inner diameter of pipe, L=length of test section, ΔP=pressure loss, V_m=mean velocity, l=fibre length of paper, γ_p=specific weight of paper slurry
δ=thickness of thin layer of water, ρ_p, ρ_w= density of paper slurry and water, μ_w=viscosity of water, χ_w= shear stress, α n₁= constants.
