What is the flow for 44mm Hi-Combat?

Explanation:
Flow is determined by the nozzle’s opening size and the operating pressure. The 44 mm Hi-Combat has a fixed, nominal flow rating at the standard nozzle pressure used with this hose setup, which is 550 litres per minute. That makes 550 LPM the expected, tested flow for this specific nozzle size. The other numbers would correspond to different nozzle openings or pressures, not the established rating for the 44 mm Hi-Combat. Keep in mind that actual flow can vary with changes in discharge pressure, but the rated value for this nozzle is 550 LPM.
