Use the Fluid node to define the density, dynamic viscosity, and heat convection and conduction properties.
The Pressure Work section has an
Include pressure work check box where a pressure work term can be activated. When checked a contribution to the right-hand side of the Heat Transfer in Pipes equation is added.
The default Heat capacity at constant pressure Cp (SI unit: J/(kg·K)),
Ratio of specific heats γ (dimensionless), and
Thermal conductivity k (SI unit: W/(m·K)) all use values
