Hello Im trying to design hvac ducts for a project, the specification call for P3 Ductal board, but I havent found friction loss charts to start my calculations, anyone knows of any source I might find the info??

Don't know if this helps. It was easy to do, try it some time.

If this site doesn't help, go find your own.

Please understand that designing ducting systems is quite laborious process - you need to know a lot before you can do sizing - Air/ Gas physical characteristics, dust/ solids size, density, carrying velocity, etc.

Complete duct system layout with type of pick-up/ collection point, type of energy booster - induced/ forced circulation Fan/ Blower, with/ without gate pressure duct balancing, and of-course the friction/ velocity losses and many time plume specification.

All the Best
