Can anyone give me some assistance on this problem: I have a pump below a sump of 1m high and pumping upward in a pipe that splits near the end. I require at least 140kPa pressure on EACH pipe. I know I need to enter the pressure in terms of head into the total head (physical height - suction height + total head loss) required, but what happens with the split? Do I add 140kPa to the total head required, or do I add (2 x 140kPa)? Thanks!
