Tank Shell Correction Calculation

Use the Tank Shell Correction Calculation to determine an adjustment factor for correcting the gross volume after a tank shell expansion caused by changes in temperature. The value of this factor is a function of the following variables.

• Tank shell temperature
• Tank shell expansion coefficient
• Actual temperature of liquid in tank
• Ambient temperature in the Case of an insulated tank

Information on the shell material type is taken from the Analysis Framework table SF_Steel Data. See Using the Steel Data Table for information on modifying this table.

\The tank type links below provide equations that describe the calculation procedure for correcting the gross volume of a tank using the Shell Temperature Correction Factor. The method involves the calculation of the tank shell temperature, then calculating the correction factor, and finally applying the factor to the gross volume.

Two types of tanks are considered:

• Uninsulated Tanks
• Insulated Tanks

See Configuring - Tank Shell Correction Calculation for details on how to configure these tank types.
