The long cylinder is rotating counterclockwise with a constant angular velocity of 80 rad/s. If the air is blowing at a constant speed of 20 m/s, determine the location of the stagnation points, and find the absolute pressure at point A. The absolute pressure within the uniform flow is 98 kPa. Take

_a
= 1.20 kg/m³.
