Consider the air flow over a 4° half angle wedge at zero angle of attack. the freestream velocity v[infinity], density rho[infinity], and pressure p[infinity]are 500 m/s, 1.23 kg/m3, and 1.01 × 105 n/m2, respectively. the pressure on the upper and lower surfaces of the wedge are constant with distance s and equal to each other, namely, pu = pl= 2.0 x 105 n/m2, and the pressure on the base of the wedge is equal to p[infinity]. the shear stress over both the upper and lower surfaces is τw = 500s-0.2. ignore the shear stress on the base of the wedge. the chord length c, of the wedge is 1 m. calculate the lift and drag coefficients for the wedge. hint: take a look at example 1.1 in thetextbook for getting started.
