Company Background and Software
LMNO Engineering, Research, and Software, Ltd., is located in Athens, Ohio (USA), and was formed in 1998. It is owned and operated by Ken Edwards, Ph.D., P.E., and Debbie Edwards, EIT. Our address and phone are 7860 Angel Ridge Rd., Athens, Ohio 45701, (740) 707-2614. Our e-mail address is LMNO@LMNOeng.com.

LMNO Engineering is a software development, consulting, and education 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 of gases and liquids including pipes, culverts, weirs, flumes, orifices, nozzles, venturis, open channels, groundwater, and hydrology. We also have software for computing tank volume, unit conversions, and molecular weight. We have recorded videos of fluid mechanics experiments. Fluid flow encompasses the disciplines of civil, mechanical, chemical, environmental, nuclear, and hydrogeologic engineering; and science.

While visiting our website, you may notice that some of the calculations are partially disabled. These calculations will become fully enabled by paying a nominal fee. Purchases can be made on our registration page.
