Use a 3D panel code to calculate the lift and (induced) drag of a rectangular wing at an angle of attack of 5◦. Assume aspect ratios of 5, 7, and 10, and compare with calculated results based on Eqs. (8.101) and (8.102).

Calculate the laminar flow inside a long cylindrical pipe for Re = 50, based on the pipe diameter. Assume uniform velocity profile at the entrance to the pipe. How long does it take along the pipe (in terms of diameters) before the velocity profile becomes parabolic, as in Eq. (5.79)?
