Thanks for the help guys! I'm starting to see where I went wrong with my original calculations (I'll admit I was a C student in high school physics, though I do enjoy trying to understand how fusion reactors work.) Yes the keg does lose some N2 when coffee is dispensed. The dissolved N2...

Sorry about that. My mind slipped when writing that. The keg volume is 1.893 liters and the nitrogen tank is .1182 liters. Tonight I tried a real-world experiment to see what would happen (plus I wanted some coffee.) I hooked the mini keg up to my large N2 tank and set the regulator to 30 psi...
