Consider a flat plate at zero angle of attack in an airflow at standard sea level conditions (p∞ = 1.01 × 105 N/m2 and T∞ = 288 K). The chord length of the plate (distance from the leading edge to the trailing edge) is 2 m. The planform area of the plate is 40 m2. At standard sea level conditions, μ∞ = 1.7894 × 10−5 kg/(m)(s). Assume the wall temperature is the adiabatic wall temperature Taw. Calculate the friction drag on the plate assuming a turbulent boundary layer for a freestream velocity of (a) 100 m/s, and (b) 1000 m/s.
