Check the actual sprinkler spacing, K factor and calculate the minimum
end head pressure. See if it matches the minimum in the calc. Also
check if all the heads in the remote area are flowing.

Reviewing a hydraulic calc for a 0.58 over 2000 gridded warehouse

All seemed OK until I reached the BOR flow of 1143 gpm. From this I
assume
the selected design area isn't correct since there's no way a 0.58
over 2000
system should flow less than 1160 gpm. I've never heard of hydraulic
imbalance that results in lower overall flow. Am I crazy or is there
a new
version of sprinkler hydraulics out there?
