Calculation method
Calculation method
RPM, required runtime hours, energy kWh table
For each measured point runtime=volume/flow, energy=runtime×power; compare only entered measurements.
Lowest-energy tested speed (rpm)
For each measured point runtime=volume/flow, energy=runtime×power; compare only entered measurements.
Symbols and units
- a
- Tested speeds JSON [[rpm,flow m³/h,power kW],...]
- b
- Required processed volume (m³)
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
- Measured points only; no assumed pump affinity curve or minimum filtration 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. Measured points only; no assumed pump affinity curve or minimum filtration recommendation.
