A 1-meter-tall tube with 50 sections, filled with granular sand and stones
Thread Content
What specification of pump should be chosen, with water entering from the bottom of the aforementioned pipe and exiting from the top?
“For a 1-meter-high tube with 50 sections, filled with granular sand and stones, what specification of pump should be chosen, with water entering from the bottom of the tube and exiting from the top? ” The flow rate of water? What is the straight-line friction factor of this 1-meter-long DN50 pipe filled with sand? (Because the diameter of these sand particles is related to the head pressure required for selecting the pump.)
Will fully packed sand and gravel be sucked into the pump?
Thank you. I’m looking for an approximate reference coefficient for calculation; perhaps I’ll just have to try it out
