On our end, we need to pump clean water; the outlet pipe has a diameter of 160, with a flow rate of 30 cubic meters per hour. The water needs to be delivered to a location 4 km away, with a total height difference of no more than 20 meters. Along the way, some sections of the pipeline are buried 10 meters underground, while other sections are exposed above ground at a height of 10 meters. How should I choose this pump? ? ? ? ? ? ? ? ? ? ? ? ? ? ?
Choose a flow rate of 30 cubic meters, a head of 20 meters, and add 5 meters due to pipeline resistance.
The loss due to the total pipe length, plus the total height difference, constitutes the head
The pipeline friction loss is around 120 meters, plus 20 meters, resulting in approximately 140 meters
