Flow rate after branch for filtration unit
Flow rate after branch for filtration unit
(OP)
I would like any help in calculating the flow rate after a branch required for a side loop filtration unit. Currently the position for the system take a branch after the oil pumps and loop back into the system with a branch to a return line going to a surge tank.
The system has a 6" header after the pump at about 190 m^3/h (900kPa). After taking a branch of 6" the pipe would need to be reduced to 3" for flanged connection. I would like to be sure that the pressure drop of our design will allow the fluid to flow back into the system at the return line.
Attached is a very crude sketch which may assist. You may see a better option than the design proposal in question.
Appreciate any help.

We will design everything from now on using only S.I. units ... except for the pipe diameter.

Will this be a matter of iteration to determine flow at the branch? Thanks.

It is likely that, if you want to protect against discharge line surges, going back to the suction is the wrong thing to do. That simply raises the suction pressure, which will also tend to increase the pump's discharge pressure even more.
