Note on the motion of fluid in a curved pipe
W. R. Dean,J. M. Hurst +1 more
TL;DR: In this paper, it is assumed that the actual secondary motion is replaced by a uniform stream; conditions in the central part of the section mainly determines the motion and the appropriate velocity of the stream can be determined from the relation that has been found experimentally between the rate of flow in a curved pipe and the pressure gradient.
