Ferm gas keg purging numbers

[SanPancho]

Too hung over to get my head straight here.

Long story short, ive got a keg thats F’d bad inside. But im thinking i can use it to get pure co2 into my cleaned serving kegs. We’re talking about 2.5 to 3 gal kegs here. If i linked up two or three of the smaller ones, kept a spund on the end to maintain pressure and keep lids closed tight, how much sugar do i need in the ugly fermenting keg to get near_zero DO in the little ones?

FERM - SERV-SERV-SERV-SPUND

@doug293cz did the math somewhere, and my takeaway was a 5G batch at regular 1050 OG was really pretty good enough to flush a single 5G vessel linked the way you intend.

I vaguely remember that but i think its buried deep in some debate thread.
