Development of a computer-aided learning system for unit operation

Abstract

This research has an objective to develop a computer-aided learning system for Unit Operation which is a fundamental subject in chemical engineering field. The main concept of this work is based on the laboratory direction of Unit Operation Laboratory course, which is a course taught in Department of Chemical Engineering, Faculty of Engineering, Chulalongkorn University. The basic unit operation selected here are Filtration, Sedimentation, Sieve Analysis, Efflux Time of a Tank, Flow in Pipe, Fluidization, and Mixing. Each unit has two main sections, calculation and theoretical sections. Turbo C++ for Windows compiler was used for compiling source code of calculation section. Meanwhile, theoretical section was developed using Help Compiler affiliated with the Turbo C++ for Windows compiler. The results using the program are presented both numerically and graphically. From investigation, it is found that there is no significant difference in calculation results compared between this program and other calculating methods. The theoretical section provides information on the selected unit in Thai with a lot of colorful pictures and keywords.
