Study 2. Working with Physical Quantities: Problems and Solutions

2-25-eng.pngThis study deals with the use of dimensional quantities in thermal calculations. The main aspects of work with dimensional variables in thermal calculations are given. The concepts of physical and empirical formulas are extended by pseudo-empirical formula concept. Few samples are provided.

You can download sheets of figures:
