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.
