If you buy a beer
If you buy a beer that is 5% ABV that does NOT mean there are 5 mL of ethanol to ever 95 mL of water. In this video we look at why that is the case and how we convert Alcohol By Volume to a mass and mole fraction. I also think I've spotted some mistakes in Perry's Chemical Engineers' Handbook, if I am to be so bold...!
00:00 I hate volume
00:35 Mixing water and ethanol demo
02:05 Volume fraction vs volume concentration
03:28 Excess molar volume
05:10 The calculation sheet for ABV
07:22 Plotting excess molar volume
08:30 Mental masturbation

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.
