Length and all elevations are the same. Pipe should equalize with one pump discharging into both. To get the right pressure I should just figure ID of one pipe?
In a bit of an arguement, one pump discharging into two lines, you cannot combine the ID of both to figure pressure. You must figure one line to get pressure of both??? Correct? Two 4.75 do not equal one 9.5, even though they are manifolded together.
