(Iain McClatchie) :


That means more, maybe a lot more pressurant will be needed, since
the colder pressurant will contract.


Assume you use hot nitrogen as pressurant for LOX. Some N2 will turns to LN2
but some LOX could be turned into cold GOX... Given that the cycling may be
well under one second, thermal exchange may be limited.
