Calculate areas from a cross section chart??
See http://www.stfx.ca/people/bliengme/E...UnderCurve.htm for
finding area under curve If an approximation is OK here is the old chemist's way (pre-computer): Plot graph and print Cut out the cross section (A) and cut out a rectangle (B) (its area is = y-axis difference * x-axis difference) Weigh A and B to 0.001 grams Mass A/Mass B = Area A/ Area B so Area A = (Area B)* Mass A / Mass B best wishes -- Bernard V Liengme www.stfx.ca/people/bliengme remove caps from email "nated7777" wrote in message ...
