Calculate Total GPM for system-the total GPM need from the pump. Lateral 1 Flow+Lateral 2 Flow+Lateral 3 Flow+Lateral 4 Flow+Lateral 5 Row+Lateral 6 Flow 9.0 + 9.0 + 9.0 + 9.0 + 9.0 + 9.0 = 54.2 Total GPM 11. Summary Enter the minimum pipe size that allows for even distribution and the volume of liquid in the pipe from Volume of Liquid in the table.
