WebOur goal is to write two coupled differential equations that describes how the two variables - conversion (X) and pressure (P) - change with reactor length or mass of catalyst packed. 1 f P X ( , ) dw dX = 2 f P X ( , ) dw dP = 0 ' ( ) A A F −r = Variation of conversion with catalyst weight. WebI've been working with sympy and scipy, but can't find or figure out how to solve a system of coupled differential equations (non-linear, first-order). So is there any way to solve coupled differential equations? The equations are of the form: V11'(s) = -12*v12(s)**2 v22'(s) = 12*v12(s)**2 v12'(s) = 6*v11(s)*v12(s) - 6*v12(s)*v22(s) - 36*v12(s) decorative ballard covers candy canes https://turbosolutionseurope.com
