  1. Standard Friction Losses
    • Elevation per story/10' - 5 psi
    • Wye/Siamese - 10 psi
    • Standpipe - 25 psi
    • Master Stream Devices at Capacity - 25 psi
    • Aerial Devices - 25 psi
  2. Standard Flow and Friction losses of Handheld Nozzles (Per 100' of 13/4" hose except where noted)
    • Control Nozzles - NP = 100 psi
    • TFT Control Nozzle - 170 gpm  (35 FL)
    • Control Nozzle on 21/2" hose - 250 gpm (15 FL/100')

    • Solid Stream Nozzles - NP = 50 psi
    • 3/4" - 120 gpm (20 FL)
    • 7/8" - 160 gpm (30 FL)
    • 15/16" - 180 gpm (40 FL)
    • 1" - 200 gpm (50 FL)
    • 11/8" - 250 gpm (15 FL - 21/2")
    • 11/4" - 325 gpm (25 FL - 21/2")
  3. Standard Flow and Friction Losses of Master Stream Nozzles per 100' of 21/2" hose
    • Solid Stream - NP = 80 psi
    • 11/4" - 400 gpm (36 psi)
    • 11/2" - 600 gpm (78 psi)
    • 13/4" - 800 gpm (136 psi)
    • 17/8" - 900 gpm (171 psi)
    • 2" - 1000 gpm (210 psi)

    • Distributor Nozzle - NP = 100 psi
    • Control - 1000 gpm (200 FL)
  4. Sprinkler System Flows
    • Pump at 150 psi
    • Standard 1/2" head flows 20 gpm at 15 psi
  5. Dual Pumping
    • Two Pumps working off of a single hydrant.
    • In order to use, measure drop in intake pressure once attack lines are in service. 

    • up to 10% = 3 like volumes remaining
    • 11-15% = 2 like volumes remaining
    • 16-25% = 1 like volume remaining
  6. Six Principles of Pressure
    • 1. Fluid pressure acts perpindicular to any surface on which it acts
    • 2. Fluid pressure at a point in a fluid at rest is the same intensity in all directions
    • 3. Pressure applied to a confined fluid is transmitted equally in all directions
    • 4. The pressure of a liquid in an open vessel is directly proportional to its depth
    • 5. The pressure of a liquid in an open container is directly proportional to the density of the liquid
    • 6. The pressure of a liquid on the bottom of a vessel is independent of the shape of the vessel
  7. Atmospheric Pressure v. Water Pressure
    • 14.7 psi at sea level
    • 12.6 psi in Salt Lake City
    • Drops 0.5 per 1000' of elevation gain
