Flow rate at outlet

mnolan93 · November 22, 2015, 16:03

Hi all,

I need to calculate the flow rate at the outlet of my problem. However I'm not sure how to do this (pressure inlet, and pressure outlet bcs are used).

Any advice?

Thanks!

I don't understand your question, but I think you should to use a Report->Fluxes

I have a 2d pipe and I define the gauge pressure at the inlet and 0 gauge pressure at outlet. I need to find the flow rate at outlet.

Thanks for your advice!

Hi,

Set your BCs and run the simulation. Then click Reports > Fluxes > Select mass flow rate and the boundaries > compute.

As alreaready reported check report-->fluxes, select outlet and read your flow rate.

Important: that value is calculated taking into account the value of "Depth" in the reference value panel, for the 3rd dimension.
