This button generates a report of the Protector Vulnerability analysis as shown below.
Vulnerability Report Tools
Print - Send a copy of the Fire Flow Report to the printer.
Copy - Copy the Fire Flow Report to the clipboard to be pasted in another application.
Sort Ascending Order - Sort selected column in ascending order.
Sort Descending Order - Sort selected column in descending order.
Decimal Places - Select the number of decimal places to display in the selected column.
Pressure Units - Select the pressure units to be displayed in the report.
Close - Close the Vulnerability Report.
Pipe ID - The ID of each pipe selected for the Vulnerability analysis.
Status - The status of each pipe following the completion of a successful run is shown here. There are two possible choices for pipe status:
Pass - This implies that failure of the corresponding pipe will maintain system hydraulic reliability and all demand nodes and minimum pressures will be satisfied. For this situation, a “Flow Condition” of “OK” and a zero “Pressure Violations” will be reported.
Fail - This indicates a network hydraulic failure and can mean either that the pipe rupture causes a system disconnection (cannot supply demand status will be prompted) or results in a situation where the minimum specified pressure cannot be maintained (critical junction node with the maximum pressure violation will be displayed) or both.
If a pipe rupture causes the network to be hydraulically disconnected then an undesirable Flow Condition of “Cannot Supply Demand” will be reported; otherwise if the system remains hydraulically connected a Flow Condition of “OK” will be prompted. If a pipe rupture results in a system that is hydraulically connected but is unable to deliver the minimum specified pressures, a Flow Condition of “OK” will be reported along with the number of junction nodes that failed to meet the target pressures. The number of failed junction nodes will be displayed in the corresponding Pressure Violations field and the junction node with the maximum pressure violation will be reported in the Critical Node ID field.
Flow Condition - Two possible results may be presented in this column.
OK - Indicates that the system remains hydraulically connected after rupture of the corresponding pipe.
Cannot Supply Demand - Indicates breaking (closing) the corresponding pipe causes a system disconnection.
Pressure Violation - The number of junction nodes that failed to meet the target minimum allowable pressures when the corresponding pipe shown in the Pipe ID field is ruptured.
Average Pressure Violation - Average value of the pressure violations when the corresponding pipe is ruptured.
Maximum Pressure Violation - The Maximum single pressure violation when the pipe shown in the Pipe ID field is ruptured. This value is computed as the difference between the target minimum pressure and the calculated pressure when the corresponding pipe is ruptured.
Critical Node ID - The junction node with the maximum pressure violation.
