All values are mean ± SE of triplicates

Different small alphabetical letter indicates significant difference between the samples

Different capital alphabetical letter indicates significant difference between the concentrations of particular sample

Different roman letter indicates significant difference between the temperature of particular sample and concentration

Value of n was less than 1 which proves sample to be non-Newtonian fluid, hence its effect can be negligible
