Calculation method
Calculation method
Hydraulic power (kW)
Hydraulic P=ρgQH; multiply by supplied turbine and generator efficiencies, with net head already accounting losses.
Electrical power (kW)
Hydraulic P=ρgQH; multiply by supplied turbine and generator efficiencies, with net head already accounting losses.

Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Hydraulic P=ρgQH; multiply by supplied turbine and generator efficiencies, with net head already accounting losses. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
