Question: air flows over a 05 m2 surface with a velocity...

Question details

Air flows over a 0.5 [m2] surface with a velocity 25[m/s] in a manner such that the pressure gradient is small. The shear drag on the surface is 200 [N]. Use the square root of the area as the characteristic length and evaluating properties at 300K. Calculate the Nu # using a. The Chilton-Colburn Analogy b. An appropriate flat plate correlation.
