Calculation method
Calculation method
Hydraulic power (kW)
P=rho g Q H; input=P/efficiency.
Estimated shaft/electrical input (kW)
P=rho g Q H; input=P/efficiency.

- Combined efficiency fraction
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
- Efficiency meaning must match the requested shaft or electrical boundary. 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. Efficiency meaning must match the requested shaft or electrical boundary.
