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.
