Example: The average pressure and shear stress acting on the surface of the 1m square flat plate are as indicated i nthe Figure. Determine the lift and drag generated if shear stress is and is not neglected.
Given: alpha = 7deg, pTa = -1.2 kN/m*m, pBa = 2.3 kN/m*m tauTa = 5.8e-2 kN/m*m, tauBa = 7.6e-2 kN/m*m
Find: D and L with and without shear
Next week, get ready to study some internal flows!
