LMNO Engineering is a software development and consulting firm. Our software goal is to have a website where practitioners, governments, educators, and students can find an organized collection of powerful, useful, yet easy to use programs. Our specialty is fluid flow including pipes, culverts, weirs, flumes, orifices, nozzles, venturis, open channels, groundwater, and hydrology. We also have software for computing tank volume, unit coversions, and molecular weight. These programs encompass the disciplines of civil, mechanical, chemical, environmental, nuclear, and hydrogeologic engineering; and science.

In addition to software development, LMNO Engineering provides consulting in the areas represented by our software. As you surf through our website, you may notice that some of the calculations are partially disabled. These calculations will become fully enabled by paying a nominal fee. In addition to running the calculations via the internet, the calculations can be purchased to run as stand-alone programs which do not require an internet connection. To enable the website or purchase the software, please visit our registration page. All of the software developed by LMNO Engineering is represented on this website.
