For insulated tanks:
Setting the Tank Material to "Other" allows the user to manually enter the ExpCoef
and the AreaCoef.
Gross Observed Volume (GOV)
The strap volume value needs to be corrected in order to arrive at the Gross
Observed volume data. The exact calculation used is dependent on the how the
tank point was configured. The following correction methods are available:
Default
The following formula is used to calculate Gross Volume:
Where:
Pre 1980
If a volume correction method with the 1980 designation is selected. The following
formula is used to calculate Gross Volume:
Where:
Japanese correction methods
If a volume correction method with the 'Japan' designation is selected. The
following additional options are available:
Ta = Tl = Liquid temperature
GOV = [(TOV-FW) x CTSh] +/- FRA + CORRVOL
TOV = Strap Volume at the current tank level
FW = Free water + Tank Bottom Solids (if any)
CTSh = Tank Shell Correction
FRA = Floating Roof Adjustment
CORRVOL = Un-measurable volume associated with tank pipe work
GOV = TOV +/- FRA + CORRVOL
TOV = Strap Volume at the current tank level
FRA = Floating Roof Adjustment
CORRVOL = Un-measurable volume associated with tank pipe work
GOV = (TOV-FW) +/- FRA - (1.0 – %BSW/100.0) + CORRVOL
