The time/WQ routine requires the designation of twelve basic types of time/WQ simulation data (over-and-above that which is required for steady state analysis), viz.:
•Water demand categories and fluctuations
•Reactions Coefficients for Pipes and Tanks
In addition, Fire Flow Simulation Data, Pump Schedule Allocation Data, Curve Data, Pump Cost Parameters, and Pipe Reaction Coefficients can be specified in separate data editors.
Some of the time/WQ simulation data are directly associated with elements of the system model, and are also saved as part of the system data. This “system-specific” time simulation data includes:
- Initial status of links (pipes, valves, pumps);
- Initial water quality of nodes (tanks and demand nodes);
- Bulk, Wall and Tank Reaction coefficient for pipes and tanks;
- Tank bottom elevations, min/max water levels, initial water levels and volume versus height specification;
- Breakdown of node base demand into (up to 5) demand categories, and assignment of time pattern ID’s to each category;
- Time pattern ID for scheduling of pumps;
- Efficiency curve, Energy price, and Energy price time pattern for pumps;
- Mixing model, Two compartment fraction, and Bulk reaction coefficient for tanks;
- All the curve related data is stored in the Curve Table, as part of System Data.
Other time/WQ simulation data cannot be directly linked to system elements. This time/WQ simulation-specific data is saved separately in a time/WQ simulation file, and includes:
- Times-, Quality-, Reactions- and Energy Settings;
- Time Patterns;
- Fire Flow Simulation Data;
- Link Controls;
- Node Controls;
- Water Quality Source definitions.
Both the system-specific time/WQ data and the simulation-specific time/WQ data can be edited in the spreadsheet editors provided. The system related data can also be entered/edited in the Albion environment, either individually for each link/node, or by using the selection options available.
