Drag measurements were taken for a sphere with a diameter of 5 cm moving at 4m/s in water at 20 degrees Celsius. The resulting drag on the sphere is 10N. For a balloon with a 1m diameter rising in air with standard temperature and pressure determine (a) the velocity if Reynolds number similarity is enforced and (b) the drag force is the drag coefficient is the dependent pi term.
