I'm setting up my draft line in a new brewpub and need help from fellow probrewers.
First of all, do you need to factor in head pressure for 7 bbl. serving tanks that are on the same floor as the draft tower? The top of the beer in the serving vessel should never be above the taps in my scenario(It's almost at the same level as the tower taps)
According to my equation from the ABG dispense chapter regarding choker lenth(y):
Dispense pressure=tank pressure-line lenth*line resistance-tap loss-3psi/ft(y-unknown choker length)
So, in my case for my longest run,
.5 psi=(12)-(54ft)(.06psi/ft-5/16" barrier tubing)-(.5psi)-(3psi/ft)(y)
.5psi=(12psi)-(3.24psi)-(.5psi)-3ft(y)
.5psi=(8.26psi)-3psi/ft(y)
3psi/ft(y)=7.76psi
y=2.58ft. choker hose
Does this look right?
Do I need to add any head pressure to this?
Anything i'm missing?
Thanks,
