What does horsepower (water) represent?

Horsepower (water) is the theoretical mechanical power transferred or required to move water against a specific head in hydraulic systems.

How is kilojoule per second related to other power units?

Kilojoule per second (kJ/s) is equal in magnitude to a kilowatt and represents the rate of energy transfer of 1,000 joules per second.

Why convert horsepower (water) to kilojoule per second?

Converting to kilojoule per second aligns hydraulic power measurements with SI units for compatibility with electrical and thermal power analyses.
