suppose you have a valve and you need to calculate CV coefficient.
This homepage shows its formula:
As you can see, the CV coefficient formula changes depending on:
- the type of fluid (e.g. liquid, gas, steam)
- the flow regime (laminar or tubulent, and therefore it depends on the Reynolds number)
Isn't there a way to automate creation of the CV coefficient formula depending on the fluid and flow regime ?
Or do you just have to re-create the CV formula everytime from scratch ?
