Pressure drop along a line.
Pressure drop along a line.
(OP)
Hi
I have been posed a question by my EH&S manger, so looking for quick reply!
I have calculated pressure required to move a slurry along a line by pressurising a pressure rated tank, connected to a 6" line approx 100m long and 18m head, to a tank vented to atms.
The MAX pressure I have calculated (inc bend,valves etc and 18m) is ~5Bar g.
His question is will we still have 5 bar at the exit of the pipe into the open tank???
I do not belive so becuse the pressure tankes into account the pressure drop along the line etc?
Can someone verify that given statment, assuming that material moves and not sealed?
Thanks

I used a flow rate of 30,000 L/hr.
Based on transfering approx 8,000 L in ~15 mins.

The tank is vented to atms, with plenty of open area.
Only when the tank is nearing full would there be any possiblty on entrainment.

When the pipe is empty of slurry there will be very little pressure drop in the air flow.

1 In directly we already preform this task! We currently vac out from one tank into a road tanker. Road tanker drives to other side of site, and blows slurry up into tank. Project is to remove need for tanker i.e install pipeline. Therfore we already preform this task with no issues!
2 We have level control and ultra high linked to block valves with set points with a max fill of 90%
3 Mist eliminator pads will be fitted to the to as a final precation.
