This was fantastic. Thank you guys.

Were did u get the 1.75

[@mnfirefighter813]

175 gallons per minute divided by 100

Based off 15/16 tip on a smoothbore hand line nozzle flowing 175gpm at 50 psi

[@danielflores-xk2iy]

I can find this formula in NFPA, What number ?

[@danielmeyers3467]

Heck with all this....give me 150psi on the nozzle with 200 feet of 1 3/4 hose... 250 psi or 250gpm Caculate that.

[@Mcgyver356]

330psi pdp.

[@johnnymitchell952]

Why the heck would you want 150psi on the nozzle?
