In addition to charts for numerous results parameters, TdhNet can chart the performance characteristics for any combination of pumps. This feature alone makes TdhNet an essential tool in your bag. TdhNet will calculate and chart a pump curve for any specified pump speed and will even calculate the pump speed needed to intersect a specified flow/head point.
Contour lines provide an easy to grasp visual display of hydraulic results.
Any number of raster images can be used as a background, set to any transparency.
These 2 images show the Query Dialog for model results and some Query Results. The Query Dialog provides an easy to use interface for common queries and provides the SQL code for modification if a more specialized query is desired. It is possible to step through the query results for a times series analysis by clicking on the -/+ buttons between the Execute and Save button. Queries can be saved and retrieved for future use.
These 2 images show the Rule Edit dialog and the Rule Builder dialog, which helps create valid rules. Any number of rules can be created and rules can be grouped into Control Sets, which can be make active or inactive at any time in a time series analysis. Rules are implemented in order of the user specified priority and a higher priority rule will pre-empt any lower priority rule for a given solution.
Many different parameters from the results of a time series analysis can be charted using the Chart dialog. For example, water elevations for any number of tanks can be placed on a single chart for easy comparisons. All the parameters for the chart, such as axis increments, can be controlled using the Chart Edit dialog
These 4 charts display the results of a pumping cost analysis. From these charts, we can conclude that pumping cost per volume increases significantly when Station 3 is operating. Even though station 3 has good efficiency, it is a high head pumping station.
