For pump, Design flow means Normal Flow.
Rated flow means Normal flow multiply by some factor.
That factor may be 1.1 / 1.2 / 1.3 depending on system.
1. Why we apply multiplication factor ?
2. Why different multiplication for different system ? i.e. for Feed/Product/Recycle it is 1.1 For Reflux it is 1.2 For BFW it is 1.3
