Orthobaric density refers to the density of a substance at a specific pressure, typically at a reference pressure of one atmosphere (atm) or 101.325 kPa. It is used in contexts where the density of a fluid or gas must be specified at a defined pressure, particularly in relation to conditions that may differ from atmospheric pressure.
