Question

7.11. USING THE SPLINE METHOD ONLY, an important fuid property is the kinematic viscosity which deter- mines the viscous, or frictional, forces acting in a fow. The kinematic viscosity of air multiplied by 10s is given at 350, 450, 500, 550, and 650 K as 20.92, 32.39,38.79,45.57, and 60.21 m/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 m2/s and 52.69 x 10-6 m%, respectively. Also, solve the problem using the interpl command in MATLAB, and compare the results with those obtained earlier
