TUBING
CHART A
SELECT TUBING & MULTIPLIER Find the dark blue cell that corresponds with the Recommended Flow (GPH) in CHART A (left). The col- umn indicates the recommended tubing size and the number in the cell is the Multiplier, the friction in every foot of tubing. For existing systems, use the Multiplier that corre- sponds to the actual flow and tubing size. ADD EQUIVALENT TUBING LENGTHS Add the equivalent lengths of all the fittings in the system, from CHART B (below left), to the tubing length from pump to falls to find Equivalent Tubing Length . + = FITTING LENGTH IN FEET TUBING LENGTH IN FEET EQUIVALENT TUBING LENGTH IN FEET CALCULATE FRICTION HEAD Multiply the Equivalent Tubing Length in feet by the Multiplier in the dark blue cell from CHART A (above left), to find the Friction Head in feet of tubing and fittings.
