MASS
Default
Mass is defined as net standard volume corrected for density at the observed
temperature. The following equation is used to calculate Mass:
In tables where density is expressed in API, Density is calculated as:
Japanese correction methods
If a volume correction method with the 'Japan' designation is selected. The
following additional options are available:
Weight in air
Where:
Weight in a pressurized tank
The GW is the Gas weight derived by following equation.
Where:
Mass = NSV x Standard Density
Density (KG/M
3
) = 141.5 x 999.012/(API Gravity + 131.5)
NW =NSV x (ρ15 - 0.0011)
NW = Net Weight
NSV = Net Standard Volume
ρ15 = 15°C liquid density
0.0011 = atmosphere conversion coefficient
NW = NSV x ρ15 + GW
NW = Net Weight
NSV = Net Standard Volume
ρ15 = 15°C liquid density
GW = Gas weight
GD = Gas density
P = Gas Pressure
