This table provides CTL factors for correcting volumes of ethanol at observed temperatures
to the volume at either 15ï‚° C or 60ï‚° F. Use this table if the following conditions exist:
ï‚· The liquid is ethanol
ï‚· Coefficient of expansion at 15ï‚° C or 60ï‚° F is not known
ï‚· Reference Temperature is 15ï‚° C or 60ï‚° F (needs to be maintained under component level!)
Coefficient of Density is fixed at 0.84*10E-3
Test temperatures can be entered on this screen that will calculate a CTL based on the test
temperature and coefficient of expansion. The test temperature and Calculated CTL are for
informational purposes and will not be used in calculations during operations.
Note: Blend range from B0 to B40
