Floating Roof Correction Factor

You have entered the mass of the tank roof.

Floating roof correction factor. Characteristics of the tank and floating roof and are independent of the stored stock liquid. This correction takes into account the material displacement caused by the floating roof of a tank which is dependent on the material density. For example if you measure 4 inches the pitch of your roof is 4 12. External floating roof tanks of the tank types external floating roof tanks efrts demonstrated the largest change in calculated emissions with a reduction of about 17 table 1 50 502 bytes.

The floating roof correction. The system calculates the correction value when you have done the following. Emission factor documentation for ap 42 section 7 1 organic liquid storage tanks final report for u. The correction made to offset the effect of the displacement of the floating roof when no correction has been built into the tank capacity table.

This will give you the rise over run or pitch. Floating roof adjustment fra a secondary correction or adjustment for any difference between the reference density and the observed density at tank temperature when a correction for the roof has been calculated into the tank capacity table using a reference density. Free water fw. You have activated the correction factor.

The system calculates the correction value when you have done the following. This correction takes into account the material displacement caused by the floating roof of a tank which is dependent on the material density.
