# Result Table - Tee and Wye Junctions

The available results that are listed in the table vary depending upon the fluid phase state and upon the visible properties that you have selected. Figure 1 shows the normal or default rows. You can choose the rows you wish to display in the results table via the Set Visible Results Dialog. Figure 1: Available results for a dividing tee junction Only descriptions for the default results are shown in this section. If you wish to see the definition for other values click here. -- 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. Branch Flow: This is the flow that FluidFlow has calculated will be flowing through the branch pipe. Branch K: This is the calculated K value that has been used in the pressure loss calculation. The value of this K depends on the calculation method that has been selected (i.e., Idelchik, Miller, Crane, or SAE). By convention the K values are always "adjusted" and shown based on channel flow. There are some examples in the "[FluidFlow3 folder]QA IncompressibleFlow\Junctions" folder that illustrate this in more detail. Branch Loss: This is the calculated total pressure loss that occurs between the branch and the channel. For a tee total pressure loss is not the same as friction loss, because there are always separation and kinetic energy changes to take into account. In FluidFlow total pressure loss is defined (from the Energy Equation) as Δ P = (z 1 ρ 1 g + p 1 + 0.5 ρ 1 v 1 2) - (z 2 ρ 2 g + p 2 + 0.5 ρ 2 v 2 2) Branch Reference: This refers to the flowsheet reference pipe number that FluidFlow has used for the branch pipe and the node that it is coming from. The row is useful for cross-referencing your results. Channel Flow: This is the combined inlet or outlet flow, to or from the tee that FluidFlow has calculated will be flowing. For all phase states the mass flow into and out of the tee will be identical. For incompressible fluids the tee inlet and exit flows expressed in volumetric units will be identical, but this will not be the case if the temperature changes across the tee. For gas flows this represents the actual flow at the tee inlet. For two phase flow of constant quality and temperature, volumetric flow will be identical, for changing quality or changing temperature volumetric inlet and outlet flows will be different. There is no pressure loss associated with the channel flow. Channel Stagnation Pressure: This is the stagnation pressure in the channel. Composition Mass %: This is the fluid mass composition in the channel. FluidFlow determines the composition via an individual component mass balance is carried out over the tee. For a tee composition can change, for example, if two different fluids flow into a tee. Density: The fluid density in the channel. Density depends on temperature and pressure of the fluid. Straight Flow: This is the flow that FluidFlow has calculated will be flowing through the straight pipe. Note that branch + straight flow must equal channel flow. Straight K: This is the calculated K value that has been used in the pressure loss calculation. The value of this K depends on the calculation method that has been selected (i.e., Idelchik, Miller, Crane, or SAE). By convention the K values are always "adjusted" and shown based on channel flow. Straight Loss: This is the calculated total pressure loss that occurs between the straight and the channel. For a tee, total pressure loss includes friction, separation and kinetic energy changes. In FluidFlow total pressure loss is defined (from the Energy Equation) as Δ P = (z 1 ρ 1 g + p 1 + 0.5 ρ 1 v 1 2) - (z 2 ρ 2 g + p 2 + 0.5 ρ 2 v 2 2) Straight Reference: This refers to the flowsheet reference pipe number that FluidFlow has used for the straight pipe and the node that it is coming from. The row is useful for cross-referencing your results. Temperature: This is the stagnation temperature in the channel. Viscosity: The fluid dynamic viscosity in the channel. 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.
