A sphere is placed in an air stream that is at atmospheric pressure and moving at 30 m/s. Using the density of air constant at 1.23 kg/m 3 , calculate (a) the stagnation pressure and (b) the pressure on the surface of the sphere at a point B, 24°C from the stagnation point, if the velocity there is 67 m/s.
