The variation with temperature of the viscosity of air is represented well by the empirical Sutherland correlation
Best-fit values of b and S are given in Appendix A. Develop an equation in SI units for kinematic viscosity versus temperature for air at atmospheric pressure. Assume ideal gas behavior. Check by using the equation to compute the kinematic viscosity of air at 0°C and at 100°C and comparing to the data in Appendix A (Table A.10); plot the kinematic viscosity for a temperature range of 0°C to 100°C, using the equation and the data in Table A.10.

The gap between the cylinders must be very small to achieve a linear velocity distribution in the liquid. Design a viscometer that will be used to measure the viscosity of motor SAE 30 oil from 0°C to 100°C. Here you need to determine and report the following parameters: a. The dimensions of the two cylinders, lengths, thicknesses and diameters. b. The gap clearance between the surfaces of the cylinders. c. The rated power of the driving motor. d. The rotational speed of the shaft.arrow_forward
