Shin-Nihon-Kentei-Kyoukai 2
Floating Roof Tank Net volume of “Shin-Nihon-Kentei-Kyoukai 2” (Japanese
authorization organization) uses the following equation.
Where:
Shin-Nihon-Kentei-Kyoukai 3
Floating Roof Tank Net volume of “Shin-Nihon-Kentei-Kyoukai3” (Japanese
authorization organization) uses the following equation.
It does not apply the roof correction to the net volume calculation.
Where:
VCF = Volume Correction Factor
%BS
W
= Percentage of bottoms, sediment and water impurities
FRA = Floating Roof Adjustment
NSV = Net Standard Volume
TOV = Strap Volume at the current tank level
FW = Free Water
CTSh = Tank Shell Correction
ρ15 = Product Density
BSG = Strap Density
VCF = Volume Correction Factor
%BSW = Percentage of bottoms, sediment and water impurities
FRA = Floating Roof Adjustment
NSV = (TOV - FW) x CTSh x VCF x (1.0 - BS&W/100)
NSV = Net Standard Volume
TOV = Strap Volume at the current tank level
FW = Free Water
CTSh = Tank Shell Correction
VCF = Volume Correction Factor
%BSW = Percentage of bottoms, sediment and water impurities
NSV = Net Standard Volume
