4. A cylinder with a radius (a) of 0.4 m lies in the air of the atmosphere flowing at 20 m/s. Find the rotational speed and direction of the cylinder so that only one stationary crystal exists on the surface (A,8= 270°) shown. Find the magnitude and position (8) of the minimum pressure acting on the cylinder. Assume that the pressure at x=-∞ is zero. The density of air is 1.25 kg/m3. (PO-03.
