I have an existing building with a sprinkler system that is supplied by a gravity tank located on the roof.  They are modifying the first floor of the building that will require hydraulic calculations.  Is it possible to mathematically create a waterflow test  accurately, or do you need to actually perform a water flow test at the 1^st floor level?
