TimbaLanD Posted December 8, 2005 Share Posted December 8, 2005 Can someone tell me the difference between using the units of pressure "bar" and "barg"? Link to comment Share on other sites More sharing options...
insane_alien Posted December 9, 2005 Share Posted December 9, 2005 a bar is 10^5 Pa absolute pressure a barg is 10^5 Pa gauge pressure. say a pressure gauge reads 20 barg this means the pressure is 20 bar above atmospheric pressure or 21 bar absolute pressure assuming atmospheric pressure that day is 1 bar. the barg is useful for working out specifications for equipment and machinery. edit: spelt gauge as guage D'OH!
