barg

Milton what is barg? I know Pa, atm, and bar.--Paul Wormer 02:51, 10 May 2008 (CDT)

Paul, barg is "bar gauge". Bourdon tube pressure gauges display the pressure above atmospheric pressure. Thus, bar = barg + atmospheric pressure.

Just as engineers in the U.S. use psia and psig (meaning psia absolute and psi gauge), many if not most metric country engineers use bara and barg (meaning bar absolute and bar gauge). - Milton Beychok 09:54, 10 May 2008 (CDT)
