The weak secondary current that occurs in flow through noncircular conduits is studied. Equations giving the magnitude of the secondary velocities near a corner are developed. These equations are based on empirical data of primary velocity distribution. Experimental measurements of the secondary current tend to confirm the validity of the relationships and solutions.
