Notes:
1. The Tracker2 requires a minimum of 50 Psi to the inlet end of the machine (after all losses
calculated through the length of hose to be used)
2. ¼" diameter (6,4mm) nozzle is the standard nozzle used in these calculations
3. The Tracker2 requires a minimum of a 1" hose.
4. To determine if there is sufficient pressure to operate the Tracker, determine the hose
length and associated friction loss from the chart above.
