An important fluid property is the kinematic viscosity which determines the viscous, or frictional, forces acting in a flow. The kinematic viscosity of air multiplied by 10^6 is given at 350, 450, 500, 550, and 650 K as 20.92,32.39, 38.79, 45.57, and 60.21 m^2/s, respectively. Using any suitable interpolation method, compute the intermediate values at 400 and 600 K. Compare the results obtained with the values given in the literature as 26.41 x 10^-6 m^2/s and 52.69 x 10^6 m^2/s, respectfully. Also, solve the problem using the interpl command in MATLAB and compare the results with those obtained earlier. Use the cubic spline method as well.
