I have nine Sabatier reactors, each producing 1.6 - 1.7 liters of O2 per hour. Each reactor goes to a pump, three per pump. These three pumps combine to feed a fourth pump. All three of the pumps which connect directly to the reactors show 1.7L of input, and 100%/5L of output. When they reach the pump combining the three, one pump shows 5L of input, the other two each show 2.5L of input, for a total of 10. Why 10 and not 15, which should be the combined output of all three of the intermediate pumps?
