A spherical ball attached to a string hangs at an angle 0 when immersed in an airstream of velocity U = 50 m/s. Neglect only the string drag. Derive an expression for 0. Also, find its value if the ball is made of steel (SG = 8.05) with a diameter of 2 cm at 20°C. %3D Laminar: Re s2x 105 Cp 0.5 Turbulent: Re 2x 106 Cp=0.2 D.
