Naming Conventions
| Cp | Isobaric Heat Capacity | H | Enthalpy | Q | Duty / Power |
| Cv | Isochoric Heat Capacity | S | Entropy | V | Volume |
| U | Viscosity | T | Temperature | X | Quality (Vapor Fraction) |
| K | Thermal Conductivity | P | Pressure | M | Mass/Mole Flow |
| c | Component (Pure Fluid) | m | Mixture (Composition) |
Thermodynamic and transport functions are named using the following strategy:
| H | P | T |
| Output | Input 1 | Input 2 |
such as HPT calculates enthalpy (H), given pressure (P) and temperature (T) for Water/Steam using IAPWS IF-97, or:
| H | c | P | T |
| Output | Component | Input 1 | Input 2 |
HcPT calculates enthalpy given a component (fluid) name, pressure, and temperature, using REFPROP. Equally, HmPT calculates enthalpy given a mixture (from a mixture sheet), pressure and temperature.
