Why would you ever use an equal percentage valve characteristic instead of a linear one?

00:00 Intro
00:36 Quick overview of Cv and characteristics
02:14 Responses in control systems
04:28 Linear valve response on 2 km pipeline
07:13 Installed & inherent characteristics
08:53 Equal percentage valve response on 2 km pipeline
10:43 Summary & rule of thumb
11:46 Keep this in mind

Process with Pat is the place to come for perspective and to ask stupid questions. I want you to leave more knowledgeable, confident, motivated, and most importantly, curious. I also want to invigorate a field that seems tired and uninspiring, at least if you get your perspective from internet forums. These are not lectures. This is a place for you to leave thinking “Oh! That’s why...”

This channel is not only for chemical engineers anyone who works with processes should be able to find something of value here.
