Detailed Description

Fluid phase, independent of any backend's integer encoding.

Backends map their own constants onto this so that nothing above the
property layer imports a CoolProp enum -- the point of ADR-0001's boundary
is that swapping an equation-of-state library is a change inside
``props/backends/``, not a change everywhere ``phase == 6`` was written.

is_liquid_like()

bool feedtwin.props.state.Phase.is_liquid_like

(

self

)

Liquid or supercritical-liquid: dense, effectively incompressible.

Used to pick correlations -- single-phase liquid pressure drop applies
to a supercritical liquid too, and asking ``phase is Phase.LIQUID``
alone would silently route a supercritical LOX line down the gas path.
