Fluid Flow mode for the U3 example simulation

The purpose of Fluid Flow mode is to show the steam delivery pressure at a required steam flow rate. In Fluid Flow mode, all of the junctions provide a pressure balance. The pipe models set the margin to zero and use the actual pipe diameter from the pipe schedule table. We make the following assumptions:

• As in Process mode, we specify the flow at each steam consumer. We calculate the Sink pressure to determine the steam delivery pressure.
