Transport behaviour of solids
The current approach to the hydraulic dimensioning of partially filled sewers uses a differentiated sediment transport equation:
Equation 3:
with:
Q = Flow, discharge, inflow, flow rate [m3/s]
cT = Solids concentration in the wastewater
ρF = Solid density [kg/m3]
ρW = Density of the wastewater [kg/m3]
vS = Settling velocity of solids [m/s]
τ0 = Wall shear stress [N/m2]
Q = Flow, discharge, inflow, flow rate [m3/s]
cT = Solids concentration in the wastewater
ρF = Solid density [kg/m3]
ρW = Density of the wastewater [kg/m3]
vS = Settling velocity of solids [m/s]
τ0 = Wall shear stress [N/m2]
Sediment transport capacity (Q • cT)
Solid properties (cT and τ0)
Experimental values (1,64 • 10-4 and 2,96)
