Step 3: Calculate flow with automatic nozzle.<br />
Using the pressure loss constant from step 2 and the following equation, the flow with an automatic nozzle can be calculated for your<br />
particular installation.<br />
Q = (P - P )C<br />
auto in-line auto<br />
Where:<br />
Q<br />
P<br />
auto<br />
auto<br />
automatic nozzle flow in GPM (or LPM)<br />
nominal nozzle operating pressure in PSI (or BAR)<br />
Mount a graph or table of the results adjacent to the in-line pressure gauge. Deliver any desired flow by adjustment of pump pressure.<br />
3.4 STREAM TRAJECTORY DATA<br />
Figures 4A and 4B give the stream trajectory for the Masterstream Series nozzles at various flows.<br />
Notes on trajectory graphs:<br />
• Graphs show approximate effective stream trajectory at 30 degrees elevation in no wind<br />
conditions. Distance to last water drops approximately 10% farther.<br />
• Trajectories shown are for water. The addition of foam is expected to decrease the reach by 10%.<br />
• Tail or head winds of 20 MPH (30 KPH) may increase or decrease the range approximately 30%.<br />
• Stream trajectory of Masterstream 4000 based on "The Trajectories of Large Fire Fighting Jets" by A.P. Hatton<br />
and M.J. Osborne, Reference: "The International Journal of Heat and Fluid Flow", Vol 1 No 1.<br />
