Air flowing over a flat plate at 5 m/s has a friction coefficient given as C_f = 0.664(Vx/v)^-0.5, where x is the location along the plate. Using EES (or other) software, determine the effect of the location along the plate (x) on the wall shear stress (t_w). By varying x from 0.01 to 1 m, plot the wall shear stress as a function of x. Evaluate the air properties at 20°C and 1 atm.
