Quantities Appearing in Equations

This is the first video in the Equations and Solvers Supplement to SCoRE, a Self-Study Course on Reaction Engineering (https://buffalobadger.github.io/SCoRE/). SCoRE is based on the online book, “Reaction Engineering Basics” (https://buffalobadger.github.io/RE_Basics/). To avoid repeatedly saying the same thing every time I describe the numerical solution of a set of equations, I developed a nomenclature for the different kinds of quantities that appear in equations. I will use this nomenclature whenever I describe how to solve a set of equations, so it is important that you understand the meaning of each name I use when referring to the quantities that appear in equations. 0:00 Intro 1:13 Known Constants 1:43 Parameters 2:19 Variables 2:45 Additional Unknowns 3:08 Derivatives 3:43 Summary I hope you found this video to be informative. Take care. Recorded June 2025.
