Piping tools - Technical Resources / Engineering / Design Spreadsheet

1)   The intention of this page is to provide Free / Open Source files for piping engineers. It consists of tools, standard reports and user developed functions (UDF), which are included in each application.  Versions for Excel (*.xls) are for the 2003 version. Few files are *.xlsm. Few matlab files are also included.

Open Channel Flow Calculator

This open channel flow calculator will help you find water flow velocity and volumetric flow rate through an open channel, given the channel's roughness coefficient, slope, and cross-sectional area.

In this calculator, you will learn how Manning's equation works and how to use it to determine water flow. You will also learn about the most efficient cross-sections of open channels. Keep reading to start learning.

This simple program calculates the flow of water in a rectangular or trapezoidal channel using Manning's Formula. The formula is only applicable to channels that have a relatively uniform profile and slope.
