I’m looking for a company to install a system for a building at my job. I’m in Alabama. Do you have any suggestions? 9 floors.

allowable pressure drop calculated 2.46 psi, approximated 2.5 psi/100 ft length.on the video you explained for 18.48 gpm with the table of 1 1/4 but in the table you added 1 1/2", in that sense its falling below the allowable friction loss of 2.5 psi.meaning, we have to contain the pressure loss below the alloeable friction loss, not 5 psi /100 feet length you early mentioned. But on 206.4 wsfu, corresponding 48.09 gpm the pressure drop value exceed 2.5 psi, and itvwas 2.71 psi though it s less than 5 psi.. Clarify me, that pressure drop in this case must below 2.5 psi/100 ' , From our allowable friction loss calculation or thumb rule of below 5 psi/100'...
