Hi all, hope you're well!
I'm considering a boka, 5 foot column, top 1 foot will be condensor and collection "cup".
2 inch copper, 48 inches of packable column as measured from below the return
to the join with the keg at the bottom of the stack. another 1 and 1/2 inches of the sanke valve sticking up above the boiler top,
not packed, just a little extra space between where the packed column ends
and the open space at the top inside the boiler, above the liquid but below the stack and packing.
I am considering reusing my existing condensor on top of the stack.
It's already braised into a 2" copper cap with a thermport that can easily double as a vent.
10 feet of 1/4 inch wrapped in a double coil.
Here is a picture of it:
I have tried the calculators here at the site. I am having trouble reconciling with vapor flow, condensor power, and my reflux equations.
I have spent a lot of time figuring figures, but frankly, I am not inspired by confidence with my math skills.
It seems so imprecise. I feel I am constantly making mathematical assumptions,
I guess I am looking for a little reassurance...
Will it be enough?
Max flow up to pushback with a recirculating pump,
No figure for flow restriction from height as the push is offset by the downwards "siphon" effect once in motion.
Also my pump is "pushing" on it... the pump can go faster than the max flowrate through the 1/4 inch. The pump is adjustable...
I actually step down the diameter of the pump out take hose to fit it.
I push the pump higher until it maxes out and vibrates a bit, then back off til it stops and settles in.
So... 5 foot column with 48 inches packed column below the return.
2 inch column.
10 ft 1/4 inch in a coil.
Any math geeks out there?
How about anyone whose used a similiar size coil with a 5ft column?
I posted this in the boka thread but nobody answered
and in my welcome thread where I got great advice on measuring my flow rate through the condensor
but also "try it and see", which I would like to avoid, for obvious reasons.
I welcome your feedback. Even if you're not a math geek.
I know there's a lot of experience on these boards.
"You know, you can just buy that stuff right up the road" he said.
I just smiled, and said quietly, "No you can't".
