Dynamic viscosity of sludge
WebOct 10, 2024 · Rheological properties of sludge (e.g., viscosity) affect several important parameters in waste treatment processes, such as pumping, mixing and sludge … 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.

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!
