You run a simulator twice with exactly the same input, but the output of the two runs is slightly different. For example, a water mole fraction is reported as \(0.98014 \mathrm{E}-02\) and as \(0.98011 \mathrm{E}-02\), and a product flow rate is reported as 5780.723 and as \(5780.716 \mathrm{~kg} / \mathrm{h}\). (These are real values from Lab 8, Part II.) Should you be concerned? Why are the numbers different?
