Deriving equations using dimensional analysis

WebDerive ODEs from SimBiology Reactions. For model simulation, SimBiology ® derives ordinary differential equations (ODEs) from model reactions using mass-balance principles. The left-hand-side (LHS) of each ODE is the time-derivative of a model quantity and the right-hand-side (RHS) is defined using reaction fluxes that are derived from reaction … WebDeriving the dimensionless product groups Let the set of base dimensions be Sbase dimensions. We assume without loss of generality that Sbase dimensions= {I, Θ, T, L, M, J, N} corresponding to the base S.I. dimensions for electric current, thermodynamic temperature, time, length, mass, luminous intensity, and amount of matter, respectively.

WebIt's actually quite rare to use dimensional analysis to derive equations in the real world. The sorts of simple systems that are amenable to dimensional analysis are usually already well known. However it's very, very useful to use dimensional analysis to check that an equation you derive is dimensionally consistent. WebChecking Equations for Dimensional Consistency Consider the physical quantities s, v, a, and t with dimensions [ s] = L, [ v] = LT −1, [ a] = LT −2, and [ t] = T. Determine whether each of the following equations is dimensionally consistent: (a) s = v t + 0.5 a t 2; (b) s = v t 2 + 0.5 a t; and (c) v = sin ( a t 2 / s).
