Pipe Flow Calculations Forum

I was looking to get a numerical relationship between gases of different densities (In particular air, and 21% oxy/79% helium) and their volumetric flow through and orifice. Given that the they are flowing through the same orifice, same differential pressure, same temperature, etc.

Thanks, love the program.

You can using orifice calculator at:

make quick calculations and find out how density is influencing flow rate.

to calculate fluid mixture density you can use equation at:

Hope this gives some guidance...
