# Result Table - Known Flow

The available results for a known flow node are the same for each possible phase state. Possible results are shown below: Figure 1: Available results for a known flow 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. Calculated Quality: Only appears if two-phase flow exists at the boundary. The quality represents the vapor mass fraction. Composition Mass %: This is the fluid mass composition. FluidFlow determines the composition of the fluid that is leaving a network, because this is determined by the component mass balance across the network. If the flow direction at a known flow is into the network then the Composition Mass % is equal to that of the fluid specified in the Input Editor. Density: The fluid density at the known pressure node. Density depends on temperature and pressure of the fluid. Stagnation density is shown at this type of boundary. Element Type: The name FluidFlow uses to describe the element. Flow: This is the flow that has been entered via the Input Editor that is flowing either into or out of the node. Fluid Phase: The phase state that exists at the known flow node. Solids Delivered: This result is only available for settling slurries and represents the delivered flow rate of solids which is automatically calculated by FluidFlow. This can be viewed for all system outlet points and can be useful when developing initial project feasibility studies. Specific Heat Capacity: This is the calculated specific heat capacity of the fluid at the operating temperature and pressure conditions. Stagnation Pressure: The stagnation pressure at the known flow node as the fluid leaves or enters the network. FluidFlow calculates this pressure, which is dependent on the flowrate you have specified. This is the sum of kinetic and pressure energies (static pressure + velocity pressure). At boundaries where velocity is often negligible (i.e., vessels or reservoirs) static and stagnation pressures will be identical. For both inflows and outflows this is equal to the pressure calculated by FluidFlow. For gas flow out of the network at a known flow node, it is possible that the actual flow is below the flow specified via the Input Editor. This will occur if the gas velocity is at sonic velocity as it leaves the network. FluidFlow always warns in this situation. Static Pressure: The pressure that can be identified for every point in a body of fluid, regardless of whether the fluid is in motion or not. Temperature: This is the stagnation temperature at the known flow 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. At boundaries where velocity is often negligible (i.e., vessels or reservoirs) static and stagnation temperatures will be identical. For flows out of the network the temperature will be that calculated by the energy balance. For inflows FluidFlow uses the temperature entered via the Input Editor. Viscosity: The fluid dynamic viscosity at the known pressure node. 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.
