Moose 120 gallon tanks

[Mike Davis]

Just thought I'd mention that after looking on the web a while tonight I've
found that Andair offers check valves that open at less than 1 psi. This
would definitely be good for what I had in mind, but the question that
remains is whether the outboard tank could transfer completely to the
inboard tank while the inboard tank remains full. Anybody know how to
calculate the pressure of 40 gallons of fuel with a rise of about 9" above
the check valve?

Mike,

The Cessna manuals claim that fuel (gasoline) weighs 6 lb/gal. The pressure
gradient for 6 lb/gal fuel is 0.3116 psi/ft. Given your nine inch rise,
the pressure will be ~0.234 psi. Volume makes no difference.

Cheers, rj

This is encouraging since ram air should be over 1 psi that would mean that
the system could empty the outboard tank completely while keeping the
inboard tank full. I'm trying to figure out how I can model the system and
test it before taking delivery... I'll let everyone know what I come up
with.

Hi

Ram is air is much less than that. I can calculate it for you if you like.
