I've run into these on a few projects. We have convinced the GC to connect to
domestic system in the past.
In this particular project, the GC is forcing the issue to connect to the fire
sprinkler system. My question is:
Do we need to flow these and a design area for sprinklers in the kitchen at the
same time? Or can they be sized independently?
These things require as much as 70 psi. The data sheet provides a k factor and
a pressure range of 40-70 psi. The pressure range is dependent on the length of
the hood. However I can't get the vendor to provide the exact psi for it at
this time.
My thought is to use the k-factor and hit it with 70 psi. If I have to flow the
kitchen sprinklers (900 sq ft) it will cause quite the over discharge and
likely not work.
So, any ideas if I should flow them simultaneously like a rack system, or just
prove each other independently?
