Tim, I'd say the best way is to submit a new quantity kind instance for the QUDT vocabulary. You could call it quantitykind:DifferentialPressure (although we just finished refining our unit naming rules here <https://github.com/qudt/qudt-public-repo/wiki/Unit-Vocabulary-Submission-Guidelines>, and we may revisit our quantity kind naming rules. If so, we might suggest quantitykind:Pressure_Differential as the qname). Regardless, the quantity kind submission guidelines are here <https://github.com/qudt/qudt-public-repo/wiki/QuantityKind-Vocabulary-Submission-Guidelines>, where you can see what we require. The logical thing would then be to include a skos:broader relation pointing to quantitykind:Pressure. Here are the current quantity kinds that have a skos:broader of quantitykind:Pressure:
