What is the minimum flow for master streams?

• A. 1325 L/min (350 gpm)
• B. 1703 L/min (450 gpm)
• C. 1893 L/min (500 gpm)
• D. 1514 L/min (400 gpm)

Answer: (A)

Master streams are designed to deliver large volumes of water quickly to powerful effect, especially over big areas or through obstacles. Achieving a reliable, effective throw with a wide pattern and sufficient reach requires a substantial flow, and that minimum is 350 gallons per minute (about 1325 liters per minute). Flows below this can struggle to develop the proper pattern, lose reach, and fail to overcome friction losses in long hose lays or elevated positions. Higher flows may be used when conditions demand more water, but they’re not the minimum.
