If I want to see how much pressure is available exactly at the total needed fire flow, do I need to set the upper limit equal to the needed fire flow?


There are separate result fields that shows the residential and zone pressure at exactly the needed fire flow. Click the Edit button at the top of the Fire Flow Node Table and add the fields "Pressure (Calculated Residual @ Total Flow Needed)" and "Pressure (Calculated Zone Lower Limit @ Total Flow Needed)".

You can also consider a hydrant flow curve.
