Converts a flow rate between m³/s, L/min, gal/min, ft³/min and more. Pumps are rated in litres a minute, air handling in cubic metres an hour, and imported equipment in GPM or CFM, so the figures have to be brought into line.
This converts a flow rate between m³/s, m³/h, L/s, L/min, L/h, gal/min and ft³/min.
Pumps are rated in litres a minute, air handling in cubic metres an hour, and water supply by the cubic metre, all for the same quantity. Imported equipment comes in GPM or CFM, so nothing can be compared until the figures are brought into line.
A flow of 100 L/min is 6 m³/h, 1.67 L/s, 26.42 gal/min or 3.53 ft³/min. A household tap runs at 10 to 15 L/min and a shower at about 10, so 100 L/min is a great deal of water.
One cubic metre a second is 15850 gal/min, roughly the flow of a modest river.
Flow rate is the volume passing each second; velocity is how fast it moves. A narrower pipe raises the velocity at the same flow rate. The two are tied together by flow rate = cross-sectional area × velocity.
The gallon here is the US liquid gallon of 3.785411784 L. Sources using the imperial gallon of 4.54609 L differ by about a fifth.
