I'm working at a terminal that does liquid storage. I need to write a calculator that can result in a pound and gallons.

For trucks, they come in on a scale to get weighed when its full, empty the liquid, then get back on the scale empty. This scale measures in pounds. The NET is the amount of liquid from the truck.

Two questions:

Q1) -------

If the liquid is 2-Ethylhexanol, how do I convert it to gallons knowing:

a) 45000 pounds of product (net) b) Specific Gravity is 0.833 (20 °C) c) weight of water 8.3378 per gallon

is the calculation 8.3378*.833 = 6.9453817 pounds per gallon? Is so, then do I just simply multiply 45000*6.9453817 to get the gallons?

Q2) --------

After I figure out the gallons. Then I need to figure out how to do Volume Correction Factors. For example, at 72 degrees Fahrenheit, how many gallons of volume does it take up? At 60 degrees using the example above it takes up 6.945 gallons. I should multiple the 6.945*VCF. What is the formula for getting the VCF?

Answer 1

Working as a chemist in a lab, I never use pounds and gallons and would rather use the density than the specific gravity. Anyway, different places, different concepts.

You are completely out of luck looking for a general volume correction factor. There is not such thing.

The thermal volume expansion coefficients are specific to the liquid. Your only chance is find a reliable compilation of these data. The CRC Handbook of Chemistry and Physics is the first source where I'd look for these.
