The Gauckler–Manning formula states: where: • V is the cross-sectional average velocity (L/T; ft/s, m/s); • n is the Gauckler–Manning coefficient. Units of n are often omitted, however n is not dimensionless, having units of: (T/[L ]; s/[ft ]; s/[m ]). WebApr 25, 2016 · Early on, if the units do not line up, you may assume that means the equation is "false," and you'll be right almost all of the time. If one becomes a physicist, later on there is a chance the units do not line up because you have discovered a new property where no one smart has gotten the units right for you.
