... conditions; the answer is stored in the variable vol as an array, or vector. The compressibility factor is calculated and stored in the vector Z. Finally, a plot is made with pres along the x-axis and Z along ... explanations, and Appendix D does the same for FEMLAB. Appendix E demonstrates how to use Excel or MATLAB for parameter estimation, and Appendix F illustrates the mathematical me...

... sufficient to obtain a correct equation. This is a useful way to detect algebraic mistakes that would otherwise be hard to find. The ability to do this with an algebraic equation is a good argument against ... and finally a new guess on T from equation 1, and use this new value as a gauge of our old guess. NOTE: Generally you want to start the loop with a variable th...

So a major goal of the approach is to introduce computing and especially programming as a tool at an early stage ... δz taken to zero at large n to the PFR equation. We actually do the calculations for intermediate values of n and show that as n gets large the concentrations reach an asympto...

It should make sense to you that the attractive energy (U A ) is inversely proportional to the separation distance, r; that is, the further the atoms are apart, the weaker the attraction: U A =− a r m (1.9) where ... more than one bond per atom, and we must take into account interactions with adjacent atoms that result in an increased interionic spacing compared to...
