What is the equation of an equal percentage valve? What is the Cv of an equal percentage valve that is 50% open? This is something I want to answer before looking at why we would even need a valve that has an equal percentage characteristic.

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.
