[Equest-users] Loop flow calculations

I have a general question about loop flow.

 

I'm working on a project where we have very specific GPM flow rates for
the primary chilled water loop, secondary chilled water loop, pump
horsepower, pressure drop thru evaporator coils, piping losses, etc.

 

I have input all of this into eQuest.

 

However, the loop flow still calculates out to a number that doesn't
match our specs.  I guess this is to be expected, as it probably has to
do these calculations in case any of my equipment is to be autosized.

 

Is there ANY way to override the loop GPM sizing.  It appears that the
loop does not reference it's associated pump for proper sizing (which
doesn't make sense to me).

 

Or, is there really no reason to do this since the loop "size" isn't
used for anything if you aren't autosizing?

 

Thanks in advance,
