This tab is used to specify the data of the test.

 

 

Toolbar

 

The buttons on the toolbar at the top of the tab can be used to enter, copy, and paste the data.

 

Add: This is used to add a new set of measurements at the selected row.

 

Delete: This is used to delete the measurements on the selected row.

 

Cut: This will cut (remove) all of the measurements and store them in the clipboard.

 

Copy: This will copy all of the measurements and store them in the clipboard.

 

Paste: This will paste the information in the clipboard into the measurement grid. It can be used to copy measurement data from Excel, by selecting and copying the axial force and axial displacement columns in Excel and pasting them into the grid.

 

Clear: This will remove all of the measurements.

 

Set Data

 

Each set represents one measurement of the permeability. The information for each set consist of the information below depending on the options selected on the previous tab.

 

Set: This is the set number automatically added by the program.

 

Manometer Level Difference: If Specify Both Manometer Levels on the previous tab is set to No, this is used to specify the difference in levels between manometers.

 

Manometer Inlet Reading: If Specify Both Manometer Levels on the previous tab is set to Yes, this is used to specify the manometer reading at the inlet.

 

Manometer Outlet Reading: If Specify Both Manometer Levels on the previous tab is set to Yes, this is used to specify the manometer reading at the outlet.

 

Sampling Duration: This the time duration of the discharge (sampling).

 

Water Collected & Container Mass: If Water Collected Measured By on the previous tab is set to Mass, this is used to specify the mass of the water collected and the container.

 

Container Mass: If Water Collected Measured By on the previous tab is set to Mass, this is used to specify the mass of the container.

 

Water Collected Volume: If Water Collected Measured By on the previous tab is set to Volume, this is used to specify the volume of the water collected.

 

Water Temperature: This is used to specify the water temperature.

 

Hydraulic Gradient: This is the calculated hydraulic gradient.

 

Discharge Velocity: This is the calculated discharge velocity.

 

Hydraulic Conductivity: This is the calculated hydraulic conductivity.

 

Hydraulic Conductivity at 20°C: This is the calculated hydraulic conductivity corrected to 20°C (68°F) .
