Question

An important fluid property is the kinematic viscosity which deter-mines the viscous, or frictional, forces acting in a flow. The kinematic viscosity of air multiplied by 10° is given at 350, 450, 500, 550, and650 K as 20.92, 32.39, 38.79, 45.57, and 60.21 m²/s, respectively. Using any suitable interpolation method, compute the intermediate values at400 and 600 K. Compare the results obtained with the values given in the literature as 26.41 × 10-6 m²/s and 52.69 × 10-6 m²/s, respectively.Also, solve the problem using the interpl command in MATLAB, and compare the results with those obtained earlier.
