Explore chemical engineering principles using MATLAB for data analysis, visualization, and solving intricate problems
MATLAB-based Computations of Chemical Engineering Principles is an in-depth textbook that enables readers to transform classical chemical engineering principles and calculations into MATLAB-based calculations. Throughout the text, problems are solved through two methods: manually (i.e., classical) and via implementing MATLAB code (i.e., digital or software-assisted), with a focus on the latter when solving problems involving multiple steps or complex solutions, or when working with large databases, such as dealing with physical properties of compounds.
Seven appendices contain large-size MATLAB codes. In general, small-size MATLAB code is kept within the relevant chapter section. All codes have been verified using the MATLAB platform. End-of-chapter problems reinforce learning by students.
The textbook includes problems and solutions related to concepts including:
System units and measurement, process variables measurement, and measurement variations and uncertainty
Types of errors involved in measurements and energy balance applications for closed and open (flow) systems
Total and component material balances, chemical reaction stoichiometry, conversion, yield, selectivity, and chemical equilibrium
Properties of pure substances and mixtures as well as vapor liquid equilibrium for single and multi-component mixtures
Equations of state for gases
Comprehensive in scope with a plethora of helpful learning aids included throughout, this is a perfect textbook for sophomore courses titled Chemical Engineering Principles, Chemical Engineering Stoichiometric Calculations, Fundamentals of Chemical Engineering, Introduction to Chemical Engineering, or Essentials of Chemical Engineering.
