Friction coefficient of air flowing over a flat plate is given as

Friction coefficient of air flowing over a flat plate is given as Cf = 0.664(Vx/n)-0.5, where x is the location along the plate. Using EES (or other) software, determine the effect of the air velocity (V) on the wall shear stress (tw) at the plate locations of x = 0.5 m and 1 m. By varying the air velocity from 0.5 to 6 m/s with increments of 0.5 m/s, plot the wall shear stress as a function of air velocity at x = 0.5 m and 1 m. Evaluate the air properties at 20°C and 1 atm.
