Detailed Description

The fluid state a component needs to evaluate its loss.

Passed in rather than looked up: a component should not own a
:class:`~feedtwin.props.Fluid`, because the same length of tube can carry
LOX on one run and water on the next, and because it keeps the physics
testable with two floats instead of an equation of state.
