feedtwin.vessels.volume.VesselState Class Reference

Public Member Functions
float	specific_energy (self)

Static Public Attributes
float	wall_temperature = 293.15

Detailed Description

The exact state of a closed gas volume.

Args:
    mass: Gas mass [kg].
    energy: **Total** internal energy [J], not specific. Total is what the
        balance integrates, and keeping it that way avoids dividing by a
        mass that is on its way to zero.
    wall_temperature: Lumped vessel-wall temperature [K]. Equal to the gas
        temperature at rest; it lags during a fast blowdown, which is the
        whole reason it is tracked.
