The flow of submersible pump
Evaluate the flow rate. Every pump is rated for a certain flow rate, which indicates how much water the pump can move per minute or per hour. The flow rate is given in gallons per minute (GPM) or gallons per hour (GPH). Choose your flow rate based on the size of the area you need to drain, keeping in mind your required time frame for drainage.
Flow rate is the amount of liquid (volume or weight) that is delivered by the pump at the time of the unit.
Volume flow (usually used in the flow) with Q said that the unit is: m³ /s (cubic meters per second), m³ /h (per hour), l/s (liters per second), etc.
Volume flow has nothing to do with the nature of conveying fluid.
1m3=1000000cm3，1h=3600s
