1. Determine the drag force imparted to the top surface of the flat plate of Example 6.4 for water temperatures of 300 K and 350 K. Assume the plate dimension in the z-direction is W = 1 m.
2. For flow over a flat plate with an extremely rough sur- face, convection heat transfer effects are known to be correlated by the expression of Problem 6.32. For airflow at 50 m/s, what is the surface shear stress at x = 1m from the leading edge of the plate? Assume the air to be at a temperature of 300 K.
