 June 30, 2005, 22:18 Outlet with specified VOLUMETRIC flow rate #1 sKin Guest   Posts: n/a Is it possible to specify a volumetric flow rate at an OUTLET boundary? Since the density for the fluid changes dramatically, mass flow rate cannot reflect the actual case. Thanks!

But why he is doing so is not understood, since there is no conservation of volume law. Even though density changes mass should remain same, whatever may be the volume flow rate. Flow rate should be inforced only on one side. (either inlet or outlet)
