Table 3. Mean values and standard deviation of consistency index (K), flow
behaviour index (n) and yield stress ( y ) obtained from fitting experimental
data to Ostwald-de-Waele model (non-linear correlation coefficient R 2 is
included). Apparent viscosity () was calculated at shear rate of 100 s -1 .
