Hello,
I am looking at trying to get a best fit curve line, say a quadratic to the data function at the bottom of document. My intent is to program in the dP(m) for the most part, disregarding the temperature and the pressure as those don't have a drastic effect on the curve considering my dP meter is from 0 to 20" of water. (about 3% at most)
I was unsure if there is a simple way in mathcad rather than finding 3 pionts and setting my data to those 3 points for a best fit, to use the gen fit to find the coefficients.
