Ken,
I’m missing something here, so I’m trying to put my finger on it. Typically,
with nitrous hybrids, the vent (more specifically its relative throughput) is
used to control the N2O temperature and typically works quite effectively at
that. If there are temperature variations/gradients within a *vented* vessel,
then theoretically there should be a natural mixing and equalization of the
fluid as there should also be an accompanying variation in vapour pressure
within the fluid which seems an unlikely occurrence.

No, if my memory serves me, which is getting more challenging with age, it was
vented. The N2O supply was a standard "K" size steel cylinder w/o a dip tube so
it was inverted in a custom made aluminum stand. The liquid nitrous was
withdrawn by opening the hand valve manually and the test apparatus was filled
remotely by a solenoid valve as was the vent valve also a remote operated
solenoid valve. Forgot to mention type K thermocouple(s) were used for remote
temp monitoring.

Mark,
I’m assuming then we’re talking about a non-vented tank here?

To clarify: my issue/question is about temperature variation in the tank… not
reaching equilibrium with the ambient temperature.
