[Equest-users] Bi-Quadratic Coefficients

[Wilkinson, Patrick]

I have the following mass flow data for a compressor. I could select points and insert it into eQuest but I was wondering if there were a faster way to create the coefficients for the bi-quadratic curve? Can this be done in excel or is there some other program I could use?



Thanks for the help.
