A cylinder of diameter \(1.2 \mathrm{~m}\) and length \(7.5 \mathrm{~m}\) rotates at \(90 \mathrm{r}\).p.m. with its axis perpendicular to an air stream with an approach velocity of \(3.6 \mathrm{~m} / \mathrm{s}\).

Plot the tangential component of the velocity along the circumference of the cylinder.

Plot the pressure distribution along the circumference.

Find the lift force on the cylinder.
