6.4 STREAM TRAJECTORY DATA
The tables and graphs in this section give the stream trajectory for the Masterstream 4000 ER Series nozzles at various
fl
ows.
Notes on trajectory graphs:
• Graphs show approximate e
ff
ective stream trajectory at 30 degrees elevation in no wind conditions. Distance to last water drops
approximately 10% farther.
• To estimate trajectories at elevations other than 30 degrees, refer to document LTT-135, available at tft.com.
• Trajectories shown are for water. The addition of foam is expected to decrease the reach by 10%.
• Tail or head winds of 20 mph (30 kph) may increase or decrease the range approximately 30%.
• Stream trajectory of Masterstream 4000 based on “The Trajectories of Large Fire Fighting Jets” by A.P. Hatton and M.J. Osborne,
Reference: “The International Journal of Heat and Fluid Flow”, Vol 1 No 1.
• Curves C, D, and E represent trajectory data for the 2000, 3000, and 4000 settings of the 100 psi selectable nozzle
