Discussion on the questions in the Tianjin University review materials for the Registered Chemical Engineer professional exam
Thread Content
I saw a problem on reactor calculations in Chapter 6 of the Tianjin University review materials for the registered chemical engineer professional exam, which mentioned the numerical integration method; I turned to the more experienced members of this forum for advice on how to solve that problem using numerical integration

Reply to 3# wangjun8328: Numerical methods for approximating the value of definite integrals. That is, the value of the definite integral is replaced by an approximate value that is a discrete or weighted average of a finite number of sample values of the function to be integrated. The definite integral in the question cannot be calculated using conventional methods; therefore, an N-th order interpolation polynomial is used to approximate the integrand, thereby facilitating the computation. This falls within the scope of advanced mathematics; in the entrance exams, you won’t be given integral expressions that cannot be solved using conventional methods, so there’s no need to worry about this approach.
