Notes
- All functions accept temperature in Celsius, pressure in bar absolute, and salinity in grams per kilogram
- Reference states (T0, S0, P0) are required for flow exergy calculations
- Functions are based on the MIT seawater thermodynamic property library
- Properties are calculated using the IAPWS Industrial Formulation
