It depends on whether you are supplying the sprinklers or a standpipe. For sprinklers, we use 150 PSI regardless. This is the state standard from the state fire marshal. For standpipes, our hose pack (150 ft X 1&3/4 inch with wye and solid bore nozzle) gets charged at 120 PSI + 25 for the standpipe + 5 PSI per fllor of elevation. In most cases we use 150 PSI then add 10 is needed.
My department usually deploys a hotel pack the consists of 150' of 1 3/4 with a standard fog nozzle. The hydraulics work out to 175 psi pump pressure and that does not include head pressure. All the engineer has to do is add 5 lbs. per floor to reach the proper pump pressure.
