After flowing a 300 GPM line, a 6 percent drop was realized on the incoming pressure. Based on this, how many additional lines of the same flow could be added?

Explanation:
Each additional line at the same flow adds the same amount of pressure drop to the incoming pressure, so the total drop stacks linearly. Here, every line causes a 6% drop. With the first line already causing 6%, you can add three more lines to reach a total of four lines, which would produce a 24% drop (6% × 4). Adding another line would bring the drop to 30%, exceeding the allowable limit, so only three additional lines can be added.
