# Getting Started Guide

#### 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.
