C IL | Let’s say you are pumping 30’ ft of run.
With a single 90 your friction loss at 2” is equivalent to pumping 35.5’ of effective run at 2”.
With (4) 3” 90’s your friction loss is equivalent to 30 + (4)*7.7 or 60.8’ of effective friction length run at 3”.
If you look at the friction loss for PVC on the Orion chart, you can see that the friction losses for 3” pipe are basically 1/7th of the losses for 2” pipe. So even if you have twice the ‘effective friction length’ your friction losses for 3” are still only 1/3 of the 2” pipe. | |
