Equation:                ETA.L = exp(A+B/(t+C))

Units:                       [t] = °C          [ETA.L] = mPa*s

Error  :                     0.42 % (average deviation)

Parameters:           A = -5.83228 B = 1223.02 C = 110.107

Measuring range:   -20.0 to 30.0 °C

 

The viscosity at 40 °C was obtained by extrapolation from the measured viscosity curve.
