4.18 A flat plate is immersed in a Mach 2 flow at standard sea level conditions at an angle of attack of 2°. Assuming the same shear stress distribution given in Example 1.8, calculate, per unit span: (a) lift, (b) wave drag, and (c) skin friction drag. What percentage of the total drag is skin-friction drag? Compare this percentage with the 10° angle of attack case discussed in Example 1.8.

Consider a rectangular wing with NACA 0009 airfoil section spanning the test section of a wind tunnel, the test section airflow conditions are standard sea level w/a velocity of 116 mi/hr. The wing is at an angle attack of 4° and the wind tunnel force balance measures a lift of 28.43 lbf. What is the area of the wing? R.N = 3.0 X106; C̟ at angle attack of 4° = 0.4 %3D
3) An advertising sign mounted on the roof of a car is 33 inches tall, 15 inches wide and 54 inches long (airflow direction). The underside of the sign is flush with the top surface of the roof. Take air properties to be: p = 0.075 lbm/ft' and u= 1.22x10 lbm/ft.sec. Used a pressure drag coefficient of 1.2 for the advertisement sign. Calculate the total drag on the sign and the power required to overcome its effect if the car is travelling at a constant speed of a) 12 mph and b) 45 mph. Note: Provide a schematic diagram (sketch) of the problem configuration (if applicable). Every numerical calculation must be preceded by the appropriate equation. Do not forget units & dimensions during your calculations.
