November 24, 2015, 17:36	Pressure boundary conditions	#1
mnolan93 Member Martin Nolan Join Date: Dec 2014 Posts: 33 Rep Power: 11	Hi all, I need to calculate flow rate from a 2d pipe. The 'total' pressure difference between inlet and outlet is only 1 pascal. The pressure inlet be asks me to define total gauge pressure, which is fine. However outlet says only gauge pressure - I presume static pressure. Using a value of 1 pascal less than the inlet BC does not give me accurate results vs theoretical results. Can anyone advise? Thank you
