Experiments have been conducted on three geometrically similar air-foils. Since airfoils are thin, the fluid flow over airfoils can be considered to be like flow over flat plate, i.e., the streamwise pressure drop can be neglected. The width of airfoils (perpendicular to air stream) is 1.0 m. Neglect the curvature of airfoils in your calculations. The results obtained from experiments are shown below: Airfoil No. 1 2 3 Length, L (m) 1 0.2 0.5 Velocity, U.. (m/s) 10 5 10 Air temp., T.. (K) 300 300 300 Airfoil temp., Ts (K) 320 320 320 Friction force, F (N) 1 0.1 ??? We know that C = C Rem in which C, and Re, are the average friction coefficient and the Reynolds number, respectively. Moreover, C and m are two constant parameters. Find C and m.
