Chezy and Manning developed equations that are used to determine the average volumetric flowrate in open channels. This article explains a laboratory method that was developed and tested to further ...

You can draw a flowchart for processes in Microsoft Excel without using an external add-on. There are mainly two methods to do so. You can use one or a combination of both methods to create a ...

The Richards equation remains a cornerstone in the modelling of water transport within unsaturated porous media, integrating both Darcy’s law and mass conservation to describe complex water dynamics.

A new equation for accurate approximation of the Moody friction factor in the general gas-flow equation better approximates a wide range of Reynolds numbers than previously published equations. Other, ...
