Profiles of mean local velocities have been experimentally determined in a smooth, concentric, horizontal annulus having a radius ratio of 0.331. The test fluid was water at room temperature flowing steadily at Reynolds numbers in the viscous, transition, and lower turbulent ranges. The transitional profiles, obtained by means of an impact probe, are summarized and discussed. Limits of the transition zone are established, and variation of the radius of maximum velocity with Reynolds number is confirmed.
