# Result Table - Connectors

The available results for a connector node are the same for each possible phase state. Possible results are shown in Figure 1: Figure 1: Available results for a connector node. -- ID -- (aka User Number): All flowsheet elements have a unique number that is assigned by FluidFlow. It is not possible for the user to change this number because it is used as a unique identifier by the scripting module. Node numbering starts from 1, incrementing upwards, and pipe numbering starts from -1, decrementing downwards. Composition Mass %: This is the fluid mass composition. FluidFlow determines the composition of the fluid at a connector, based on a component mass balance. Density: The fluid density at the connector. Density depends on temperature and pressure of the fluid. Stagnation Pressure: The average stagnation pressure at the connector. This is the sum of kinetic and pressure energies (static pressure + velocity pressure). Temperature: This is the stagnation temperature at the connector node. The stagnation temperature is the temperature that the fluid would reach if it were brought to rest isentropically, converting its kinetic energy to enthalpy. Viscosity: The fluid dynamic viscosity at the connector. Viscosity is a measure of the resistance of the fluid to deformation. For Non-Newtonian fluids viscosity depends on shear rate as well as fluid temperature and pressure.
