STEP NO. 9 – DETERMINE NUMBER OF WATER TANKS
REQUIRED
Total water required / 50 Gal per tank = Equals number of
tanks
Example: 110.35 gallons (417.6 liters) / 50 gallons (189.28
liter) = 2.21 tanks
Round up to nearest whole number of tanks.
Example: 2.21 tanks round up to 3 tanks
NITROGEN CALCULATION PROCEDURE
Note: When calculating systems containing selector valves,
see the additional required steps detailed in the Appendix
of this manual.
PIPING and FITTING NOTES
1. When calculating the acceptable system pressure loss,
combine the supply line (A) with the branch line (either
B and C, or B and D, or E and F, or E and G) that has
the most pressure loss.
2. The maximum difference in pressure loss from the
atomizer with the greatest pressure loss to the atomizer
with the least pressure loss is 20 psi (1.4 bar).
