Something like Mathematica, Maple or MuPad might be able to help.
Just try to find some linear interpolation examples.


You may be heading in this direction already, but if I were trying to
solve such a problem, I would first go looking for an analytical solution
where you just compute the result directly. No interpolation necessary.
Then just put these values in a lookup table.

This assumes that you don't mind a little programming exercise.

The nomographs that I am familiar with are from the "old days" where
there wasn't much computing power available. It was easier and faster to
check this WA table/chart.  Now you place one edge of the ruler...
