In AlChE Journal (Jan. 2005), chemical engineers published a new method for modeling multicomponent transport of gases. Twelve gas mixtures consisting of neon, argon, and helium were prepared at different ratios and at different temperatures. The viscosity of each mixture (10^-5 Pa • s) was measured experimentally and was calculated with the new model. The results are shown in the table below. The chemical engineers concluded that there is “an excellent agreement between our new calculation and experiments.” Do you agree? Your answer should include a discussion of practical versus statistical significance.
