Learning Objectives
Upon successful completion of this module, you will be able to:
1) Understand the primary dimensions (also called fundamental or basic dimensions) from which all other dimensions can be derived,
2) Describe the fluid characteristics qualitatively in terms of primary dimensions,
3) Recognize the importance of dimensional homogeneity in engineering calculations,
4) Discuss different unit systems commonly used in engineering, such as the International System of Units (SI), British gravitational (BG) units,
5) Understand the importance of using consistent system of units (e.g., don’t mix BG and SI units) when solving problems,
6) Perform unit conversion between different unit systems.
