In your calculations you provide X gallons for firedepartment use, after you have used up Y gallons for the sprinkler system. Thefire department takes that X gallons from a hydrant through their Fire Truckmounted pump. The pump operator delivers the X gpm through the hoses at whateverPSI is their operating standard, the pressure being supplied by the truckmounted pump.

I'm sure it's the way I'm trying to explain it that's not making any sense to him, can one of you more versed in the English language help me out and put it in layman's terms for me?
