Question

(a) With the help of neat sketch, explain the circulation theory of Lift and Magnus effect.

(b) Air blows over a cylindrical smoke-stack of $5\text{ cm}$ dia with a velocity of $0.2\text{ m/s}$. Work out the total aerodynamic drag, shear drag and pressure drag on $1\text{ m}$ length of the smoke-stack. For the flow situation, the total and shear drag coefficient are $1.25$ and $0.18$ respectively.
