Alcohol by Ebulliometry
Details: This calculation corrects the ebulliometer reading based on the calibration reading, and then calculates the alcohol content.
Initially, the ebulliometer degree is calculated:
ebulliometer degree = calibration - reading
This essentially yields the number of degrees below the boiling point of water, at which the sample is boiling.
Next, a polynomial expression generated from a large data set is used to give the alcohol (% by volume):
alcohol = 0.0002590805845 * d4 - 0.0006404605357 * d3 + 0.001926392743 * d2 + 1.364664067 * d - 1.29216576
Where d = the ebulliometer degree.
