Question 3 The Sutherland's viscosity law for gases has been derived from the kinetic theory by Sutherland using an idealized intermolecular-force potential. It is given as: CT3/2 where u is the viscosity, C and S are empirical constants, and T is the absolute temperature. Following is the viscosity data for air at different temperatures. 100 µ (N.s/m²) | 1.71×105 | 1.82×105 | 1.87×105 | 1.97×105 | 2.07×105 2.17×105 T (C) 20 40 60 80 a) Using the given data for air, determine the values and units of C and S. b) How do the values change if the viscosity was determined in Ibr.s/ft? based on temperature measured in the U.S. Customary units.
