Meaning of deep well pump flow

Meaning of deep well pump flow
    Pump flow is the amount of water pumped per unit time, or pump flow is the amount of water pumped per unit time. In this case,
Deep well pump flow commonly used English letter Q expresses. Pump flow unit is m3 / s, m3 / h, L / S and so on. In this case,
If the pump flow rate is 90M3 per hour, write 90M3 / h; flow is 25L per second, write 25L / s. Because 1M3 water weight 1000kg, 1L water weight 1kg, 1h to 3600s, so different units can be converted. For example, 25 L / s = 90 M3 / h. In this case,
Pumps marked on the pump flow rate is rated flow, the pump in the flow of work under the highest efficiency. When using the pump, should strive to work in the vicinity of the rated pump flow, so the most economical. The flow rate is proportional to the pipe diameter and flow rate. When the pipe diameter is selected, the flow rate can be increased by increasing the flow rate. But the flow velocity is too high, the friction loss is increased and the efficiency is reduced. The general control flow rate is 1 ~ 3m / s.
