The Test Details tab documents details of the test, such as the time of the inspection, the device used, and flow depth. Some fields are automatically populated with corresponding data from the pipe's Inventory record. Other fields are automatically populated with calculations based on the user-entered data. See the list of calculated fields below.
Upstream Test Fields |
Functions |
US Meas Flo (gpd) |
The upstream manhole flow measured by the flow measuring device, in gallons per day. |
US Flow Depth (in) |
The depth of the flow (in inches) at the upstream manhole at the time of the isolation test. |
US Diameter (in) |
The diameter of the pipe where the upstream manhole flow isolation test was performed. The program defaults to the diameter of the first pipe in the pipe list for the US Diameter. |
US Slope % |
The slope of the pipe where the upstream manhole flow isolation test was performed. The program defaults to the slope of the first pipe in the pipe list for the US Slope %. |
US Mannings |
The Mannings number of the pipe where the upstream manhole flow isolation test was performed. The program defaults to the Mannings number from the first pipe in the pipe list for the US Mannings. |
US Calc Flow (gpd) |
The flow (in gallons per day) calculated from the upstream depth measurement using the Mannings equation. |
Downstream Test Fields |
Functions |
DS Meas Flo (gpd) |
The downstream manhole flow measured by the flow measuring device, in gallons per day. |
DS Flow Depth (in) |
The depth of the flow (in inches) at the downstream manhole at the time of the isolation test. |
DS Diameter (in) |
The diameter of the pipe where the downstream manhole flow isolation test was performed. The program defaults to the diameter of the last pipe in the pipe list for the DS Diameter. |
DS Slope % |
The slope of the pipe where the downstream manhole flow isolation test was performed. The program defaults to the slope of the last pipe in the pipe list for the DS Slope %. |
DS Mannings |
The Mannings number of the pipe where the downstream manhole flow isolation test was performed. The program defaults to the Mannings number from the last pipe in the pipe list for the DS Mannings. |
DS Calc Flow (gpd) |
The flow (in gallons per day) calculated from the down stream depth measurement using the Mannings equation. |
Calculations Fields |
Functions |
Meas Flow Diff (gpd) |
The difference between the downstream and upstream measured flows (highlighted in orange). Automatically calculated based on DS Meas Flo - US Meas Flo. |
Calc Flow Diff (gpd) |
The difference between the downstream and upstream calculated flows (highlighted in blue). Automatically calculated based on DS Calc Flow - US Calc Flow. |
Meas Flow per IDM |
The measured flow for a single IDM. Automatically calculated based on Meas Flow Diff / (Sum of IDM fields on all records in Pipes grid). |
Calc Flow per IDM |
The calculated flow for a single IDM. Automatically calculated based on Calc Flow Diff / (Sum of IDM fields on all records in Pipes grid). |
