# Result Table - Circulator

The available results for a circulator node are the same for each possible phase state. Possible results are shown in Figure 1: Figure 1: Available results for a circulator 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 the circulator, because of the closed nature of the circulator loop, the Composition Mass % is equal to that of the fluid specified in the Input Editor. Density: The fluid density at the circulator. Density depends on temperature and pressure of the fluid. Flow: This is the flow that FluidFlow has calculated will be flowing through the circulator. Stagnation Pressure: The stagnation pressure at the circulator. This is the sum of kinetic and pressure energies (static pressure + velocity pressure). Temperature: This is the stagnation temperature at the known pressure 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 circulator. 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.
