Notes: The maximum potential flow rates are calculated based upon the
displacement potentials of the pump, and assuming a 1 second reset interval.
Be sure to consider that the max flow rates are only achievable under optimum
conditions.
For example, optimum conditions would consist of normal operating temperatures, a
steady flow of vehicles or animals, and a near perfect source and input system operations.
The water line diameter needs to be properly sized because there can be significant
pressure loss in the line due to friction. For a herd of 50 cows, the system (water
source, pump/pressure tank, delivery line, valve) should be capable of supplying 0.3 Us
(4.0 imp.gpm). To achieve this, a 19 mm (3/4") diameter pipe is generally used for
lines less than 150 meters long, 25 mm (11 ") for lines of 150 to 500 meters, and 32
mm (111/4") for lines over 500 meters. Water flow requirements are less for smaller
herds.
