Transport behaviour of solids (4)
According to the study by Macke deposit free states can be reached by a steady flow, when the following conditions at the critical velocity vc are met:
Equation 5: (wastewater)
Equation 6: (combined and rain water)
The corresponding wall shear stress is determined using the equation:
Equation 7:
with
ρ = density of the wastewater [kg/m3]
g = gravitational acceleration [m/s2]
rhy = hydraulic radius (A/lU) [m]
IR = friction factor [-]
