"""Vessels: COPVs, tank ullages, manifold plenums.
 
All the same object at different sizes -- a closed volume of gas whose pressure
is what the rest of the system sees::
 
    from feedtwin.props import Fluid
    from feedtwin.vessels import GasVolume
 
    copv = GasVolume(Fluid("nitrogen"), volume=0.009,
                     wall_mass=6.0, wall_capacity=900.0, wall_conductance=12.0)
    state = copv.initial_state(pressure=310e5, temperature=293.15)
    copv.pressure(state)          # Pa, real gas
 
State is ``(mass, internal energy)`` rather than ``(mass, temperature)``, which
keeps a real gas's energy balance exact. See :mod:`feedtwin.vessels.volume` for
why that distinction is worth the trouble, and why a vessel wall is not an
optional refinement.
