The change in the viscosity of water (in mPa s) with temperature within the limits of 5 and 35°C can, within an R2 value of 0.9995, be represented by the quadratic equation: μ w = 5.829 × 10 − 5 T 2 − 4.868 × 10 − 2 T + 0.00174. Several authors have offered empirically-derived correlations between viscosity and temperature for sludge.
