The plot shows apparent viscosity versus shear rate of Newtonian, Dilatent and Pseudoplastic fluids. Based on this plot and the fluid behaviour as mentioned below, find out the correct combination.
1 = Dilatent fluid; 2 = Newtonian fluid, 3 = Pseudoplastic fluid
Answer: C
The match is P-2; Q-3; R-1.
A Newtonian fluid has a viscosity independent of shear rate: the horizontal line P. A pseudoplastic (shear-thinning) fluid's apparent viscosity falls as shear rate rises: the falling curve Q. A dilatant (shear-thickening) fluid's apparent viscosity rises with shear rate: the rising curve R.
'P-1; Q-2; R-3' calls the flat line dilatant, and 'P-3; Q-1; R-2' calls it pseudoplastic. The last option assigns Q twice and leaves R unassigned, so it cannot be a complete match.
