Deviation variables

[dscot]

Hi,

If I have two deviation variables F*Ca* and I'm asked to linearise them, how can I do this? Where Ca is the concentration and F is the volumetric flow.

I know that the answer is FssCa* + CassF* .

Thanks

Have you tried regressing the data to create an analytical function, and then a taylors series approximation of the function. Or interpolation?

That sounds familar but I'm not too sure how to go about.
