Where:
Correction volume
This is the un-measurable volume associated with line segments and manifolds
connected to the tank. The operator usually manually enters this value.
Volume Correction Factor (VCF)
This is the correction factor calculated via one of the methods defined in the
table(s) above. The value is used to correct the gross volume for the effects of
temperature.
Tank Shell Correction (CTSh)
Volume correction for the temperature of the shell. Compensates for the effect of
ambient and liquid temperature effects on the shell of the tank.
CTSh is calculated as follows:
Where:
For Non-Insulated Tanks:
Where:
FW = Combined Water and Solids volume
H20VOL = Water Volume
SOLVOL = Solids Volume
CTSh = 1 + ExpCoef x ΔTs + AreaCoef x (ΔTs x ΔTs )
ΔTs = Ts-Ref Temp (60°F)
ExpCoef =
MILD STEEL = 12.4 x 10
-6
STAINLESS STEEL = 9.6 x 10
-6
ALUMINUM = 13.0 x 10
-6
AreaCoef = 4.0 x 10
-9
Ts = [(7xTl) + Ta] / 8
TI = Tank Liquid Temperature
Ta = Ambient Temperature
