Mixing distance in a pipe
Mixing distance in a pipe
(OP)
In a water treatment plant, I need to start injecting caustic for pH adjustment. It will be in a 30" pipe with velocities in the 1.2-2.4 fps range. How far after the injection point will the mixing be complete enough so that a pH probe will give me a good indication?

Have you considered using a mixer?
Not sure why you would be injecting caustic for pH control. Use of caustic (NaOH) is going to be very expensive for that capacity. Have you considered use of lime?

30" pipe? that's a large TP.
