I find the terms pressure and head often get mixed up, here's my attempt to clarify this. Let's reveal what's behind the curtain. I'm calling this series of 3 articles "The Pump Companion"

These apps allow you to make calculations directly on a web page (no java applets) or on your mobile browser. You can calculate: velocity, head from pressure, pipe friction, N.P.S.H.A, submergence requirement, specific speed, suction specific speed and pipe dimensions. Web apps web page icon.

I am your host Jacques Chaurette and the author of this web site and most of everything in it. I live in Montreal, Canada. I have nothing to do with any pump manufacturing company and am not trying to sell you anything. Please join the Forum and ask any question you like. I can be reached at Yours truely.
The previous incarnation of this site was www.lightmtypump.com, yeah I know it seemed like a good idea at the time, I changed it to www.pumpfundamentals. The prior site to lightmypump.com was called www.fluidedesign.com it was abandonned (for bizarre reasons)and morphed into this site. Unfortunately by mistake, the domain name was allowed to lapse and someone else picked it up. Before that I had a site called www.pumpsRme.com, not very original I know, that was in 1992, everything was new then on the internet.
Yours truely
