6.1 Introduction
This chapter builds on the material provided in the previous one. Here we present some material that is normally not covered in an academic curriculum, but that is important for understanding fluid flow in industrial applications.
The conventions used with regard to units of measure will be the same as in Chapter 5.

The fluid mechanics calculation methods described herein are performed inthe EPCON Process Innovator® simulation software used by thousands of engineers worldwide.
6.2 Notation
| A | = | Cross‐sectional area, ft2 |
| b | = | Parameter in Eqs. 6.53 and 6.55, dimensionless |
| C d | = | Meter discharge coefficient, dimensionless |
| C V | = | Flow coefficient for a control valve, dimensionless |
| c | = | Speed of sound, ft/sec |
| c p | = | Heat capacity at constant pressure, (ft lbf)/(lbm R) |
| c v | = | Heat capacity at constant volume, (ft lbf)/(lbm R) |
| D | = | Pipe diameter, ft |
| D(i) | = | Set of all pipes in a network for which node i is a destination (see Eq. (6.35)) |
