Water Pump

What is flow rate?
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
We Insist On The spirit of Sincere CO-oriented High Quality Perfect Services And Sincere Welcome to Customers For Cooperation.
