Webb30 juni 2016 · These losses are called minor losses, but these losses must be considered if the piping system has a lot of such fittings. These losses are treated as equivalent frictional losses. The minor loss may be treated either as a pressure drop Δp = -KρV 2 /2 or as a head loss Δh = -KV 2 / (2g). WebbTo read a Moody Chart, first calculate the relative roughness of the pipe, ε/D. ε is the roughness height of the internal walls of the pipe and is published in many tables.

Webb2 nov. 2024 · For example, if your pipe's minimum ID at restrictions is 18mm, the flow rate would be two-thirds of a 22mm pipe. Actually, for a given head the flow through a pipe is - all other things being equal - proportional to the diameter to the power 2.5, so an 18mm pipe would carry about 60% as much as a 22mm pipe. Not that far off two-thirds, though.
