摘要：在《化工原理》课程教学中,学生对量纲分析法普遍都有理解和应用上的困难,本文旨在说明量纲分析法在单元操作应用中的关键步骤,并以流体流动阻力计算为重要的工程实例,介绍量纲分析法的思路和步骤。
This paper explains dimensional analysis means in the principles of chemical engineering.By summarizing the main steps in the course to the dimensional analysis means,based on the difficulty which students widely face in their learning,and by taking calculating the friction loss as a key example,this paper tries to make students correctly understand and make use of the ideas and steps of dimensional analysis means.
