Dynamic viscosity of sludge
WebMar 31, 2015 · The results showed that the low-solids sludge with total solids content (TS) 2–15% was pseudoplastic fluid, and the high-solids sludge with TS 7–15% exhibited thixotropic property. Sludge viscosity increased exponentially with the increasing TS, and decreased in function of power along with the increasing shear rate.

As one plane moves past another in a fluid, a velocity gradient …
WebYou can assume a dynamic viscosity for water of 0.00131 kg/m-s and a density of 999.7 kg/m² You should specify the number of sedimentation basins, the basin dimensions, and the basin overflow rate and hydraulic residence time. Sludge scrapers come in a standard 5-meter length, so your basin width should be in increments of 5 meters. WebSep 24, 2002 · If it is not kind of a thickened sludge - let's say up to 1% solid content - I would go with standard water viscosity. Vkin (kinematic viscosity) of water: @ 60^C = 4.78 * 10^-7 m^2/s @ 80^C = 3.66 * 10^-7 m^2/s Usually sludge doesn't get thick if warmed up, not until 100^C (of course!), quite the contrary happens - it gets less viscous! Good luck!

WebJan 15, 2024 · We measure internal resistance to flow as absolute viscosity (also referred to as dynamic viscosity). It is critical for the viscosity used to be consistent with “in pump” shear conditions, or shear rates of 800 or more s-1 (inverse seconds).As the following comparison shows, differences in viscosity vary dramatically by fluid:
