The Fluid Flow Calculations Website
This is the home site for LMNO Engineering, Research, and Software, Ltd. The main features of this site are on-line calculations for fluid flow, flow measurement, and unit conversions. There are over forty equations grouped by the following categories: Hydrology, Groundwater/Porous Bed, Volume, Open Channels, Pipe Flow, and More Programs. Some equations are available for free, while others require a user-fee. A few of the familiar equations are the ideal gas, Manning equation, Colebrook equation, Darcy-Weisbach equation, Hazen-Williams equation, and Bernoulli Equation. Information is provided about the company and the services that it provides. An extensive list of related links, and subscription to the free LMNO Engineering bi-weekly, electronic newsletter are offered. The newsletter contains information about calculations, applications, and website updates.

Technical requirements:
All of the calculations on the LMNO Engineering, Research, and Software, Ltd., website have been coded in Java using double precision and checked against known results. LMNO Engineering is confident that the programs work as intended; however, it cannot be held responsible for any negative consequences of using the programs. Some web browsers do not print Java applets, so we suggest using a screen capture program like SnagIt for printing the calculations.
