2-Way Flow Splitting (Discrete): Oper. Conds Tab

Variable Definitions, Ranges and Default Values

The following table shows a brief description of the variables appearing in this tab. The table also displays their default values and their generally acceptable range:

Variable	Default Value	Range

● Stream Name The output stream name connected to the respective output port.	<None>	Dedicated Output Port
○ Split % The split percentage of the feed stream’s entities to the respective output port.	0.0	0 – 100
● Total (%) The sum of the specified split percentages to all output ports.	0.0	0 – 100
● Operating Throughput per Unit (entities/h) The entities flow rate of the feed stream divided by the number of equipment units.	0.0	Positive
○ Setup Time (min) The amount of time (per cycle) spent before each operation is carried in preparation for the actual execution of the operation. It may involve actions like cleaning, vacuuming, setting up of equipment, etc. which the user opted not to model explicitly.	0.0	Positive
◙ Process Time (min) The actual duration of the operation (per cycle).	60.0	Positive
○ Ignore Labor? Check this box to ignore labor for this operation. This option is used only if the process time is set by a master-slave relationship.	Yes	Yes/No
○ Power Type Indicates the power type that is used by the operation. Click on the list box to bring up a list of available power types in order to select one.	<Std Power>	Any Power Type
◙ Specific Power (kW/(Entity/h)) The power consumed for the operation per feed entity flowrate.	0.0	Positive
◙ Total Power (kW) The total power consumed for the operation (per cycle).	0.0	Positive
◙ Power Per Unit (kW) The power consumed for the operation per equipment unit.	0.0	Positive

Symbol Key: ○ User-specified value (always input); ● Calculated value (always output); ◙ Sometimes input, sometimes output

Specification Choices / Comments

The following list describes the available specification choices in this tab; for more details on how these are implemented, see 2-Way Flow Splitting (Discrete): Modeling Calculations.

This dialog tab displays the calculated operating throughput of this operation. The percentage of flow to the top stream is specified.

•Duration Options...

The duration controls appear only if the procedure is in batch mode. In Rating Mode, you can set the process time (and the setup time), allow the process time to be calculated (based on the throughput), or allow the duration to match exactly the duration of another operation either in the same procedure or in another procedure. In Design mode, you must either specify the process time (and the setup time) or allow the duration to match exactly the duration of another operation (either in the same procedure or in another procedure).

If you choose to match the duration of this operation with the duration of another operation, you introduce a master-slave relationship between the two operations. The program will match the setup-time, the process time and the turnaround time of this operation (the ‘slave’) with the corresponding times of the reference operation (the ‘master’ operation). For more on master-slave relationship, see The Scheduling Tab.
