The General tab fields allow you to document when the smoke test took place, what crew performed the test, and the test result. The Total GPM and Remaining GPM fields are calculated by the system. These are described below:
Field Name |
Definition |
Total GPM |
This field sums the Remaining GPM values from the Source Details tabs of all records in the Observations Grid. Flow is measured in gallons per minute (GPM). GPM is calculated using the following rational formula: Q = CIA where: Q = Flow C = Coefficient of runoff based on type of surface I = Rainfall Intensity A = Area (in acres) |
Remaining GPM |
This field represents the remaining infiltration after the structure's rehabilitation. |
Note: The Flow Rate (gpm) and % I/I Removed fields (in the Observation records' Source Details tabs) must be populated for these calculations to be performed.
