Digging It: Display Flow Capacity with Manning Equation

You can use an expression for Manning’s equation to label pipes, in plan or profile view, in order to display their flow capacity. This process was developed by Jeffrey Old, a licensed P.E., and AEC Solutions Engineer with Hagerman & Company, Inc., based in Mt. Zion, Illinois, USA (http://www.hagerman.com). Jeffrey has provided advice on how to use expressions to design pipes hydraulically, as well as an explanation of how these expressions work.
