[CFD] When and Why do I need Operating Pressure, Temperature and Density?
An introduction to the concepts of operating pressure, temperature and density, as they are used in CFD. Short, concise arguments are presented for why CFD codes use them, and when you should apply them. The following topics are covered:
1) 0:42 When and why do I need an operating pressure?
2) 12:59 When and why do I need an operating density?
3) 17:31 When and why do I need an operating temperature?
