Calculation method
Calculation method
Observed flow (L/min)
Flow=collected×60/time; drainTime=volume/flow.
Same-head estimated drain time (minutes)
Flow=collected×60/time; drainTime=volume/flow.
Recorded test head (m)
Flow=collected×60/time; drainTime=volume/flow.
Symbols and units
- a
- Collected test water (L)
- b
- Collection time (seconds)
- c
- Water volume to drain (L)
- d
- Recorded test head (m)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Only measured-head performance; no automatic bilge capacity or emergency recommendation. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. Only measured-head performance; no automatic bilge capacity or emergency recommendation.
