摘要
To have any breakthrough in fluid flow study, efforts must be made to acquire a new point of view. The viewpoint or concept of this paper is that understanding of laws of nature should enable fluid flow studies to become effortless. A natural law presented herein is that the ratio of the mean and maximum velocities in a channel cross section tends to be constant and independent of discharge and water level. The law is supported by observed data, hydrodynamics, and the Chiu's velocity distribution equation derived in the probability domain on the basis of the law of nature that uncertainty tends to increase. The law of constant ratio of the mean and maximum velocities is useful in studying various transport processes in open channels and in designs of efficient methods of measuring the discharge and sediment concentration and computations of energy and momentum coefficient in open channel flows.
