I'm using the Blender fluid simulation capabilities to study a certain fluid into a vessel with certain obstacles. The only option I'm seeing for the inflow is velocity in m/s. I'm really needing something in terms of a volumetric flow rate, like cc/s or something. I thought maybe the speed multiplied by the area of the surface ejecting the fluid would work, but it doesn't appear to be very constant. (ie: there isn't a steady fluid flow, but it kinda just dribbles out)

Any hints on how to make this work correctly?
