Table 2
How to use the table above:
1. Determine the product water pressure
2. Select your tank size and see what ratio you get at 5 psi air pressure using your calculated product pressure. (Ex. 50 psi
product pressure at 5 psi for 2 gallon tank has a ratio of 69.6%)
3. If ratio is above 70% then the air pressure should be increased. Look at graph 1 to determine relative air pressure to maintain
a 70% or lower ratio.
4. Once air pressure and ratio is identified take the total tank volume and multiple it by the ratio value to get the water storage
capacity of the tank. (Ex. @10 psi air pressure (pre-charge) and 50 psi product water pressure ratio is 61.8%. Capacity for 3
gallon tank is 4.4 x .618 = 2.7 gallons)
