Webb24 sep. 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!

In the literature, a variable viscosity is often referred to as apparent viscosity. The velocity gradient affects the viscosity, resulting in a much higher (or in some cases lower) tangential stress than for a Newtonian fluid.
