Water Pump Series

The flow rate is the volume of the liquid that the pump discharges in unit time. The flow rate is expresses as Q, the measurement unit: cubic meter/ hour (m3/h), liter/ seconds (l/s)

L/s=3.6 m3/h=0.06 m3/min=60L/min   G=Qρ G is weight and ρ is specific gravity of liquid 

Example: The flow rate of a pump is 50m3/h. Please figure out the weight per hour when drawing water? Note: the specific gravity of water is 1000 kilograms/ cubic meters 

Solution: G=Qρ=50×1000(m3/h•kg/ m3)=50000kg / h=50t/h
