Lagelier Saturation Index Calculation

[@howiediep5782]

Hi, what if the readings fall in between the chart? Lets say TAF is 165 ppm, what number would you use to calculate? Or CHF is 10ppm? Do I round up or down? How would you calculate an accurate unit to use to plug into the formula? Do I round up or down? Thanks in advance!

I would generally round up to be a bit conservative. LSI is not a precise measurement, so a little rounding should not hurt your interpretation. Of course, things can vary by your specific circumstance, so looking at the rest of the numbers may dictate a different approach.
