() Q1. I) What is Newton's law of viscosity? Define Newtonian and (a) non-Newtonian fluids. II) Define Kinematic viscosity. Derive the equation for SI unit of Kinematic viscosity. III) State whether the following statements are TRUE or FALSE. i) The viscosity increases with increasing temperature, for gases at low density. ii) For liquids the viscosity usually decreases with increasing temperature. IV) Draw the graph for shear stress versus shear rate for Newtonian, dilatant, pseudoplastic and Bingham plastic fluid.
