What is horsepower (water)?

Horsepower (water) refers to the mechanical power used to move water against a certain head, calculated based on flow rate and head height.

Why convert horsepower (water) to foot pound-force per hour?

This conversion is useful for expressing modern hydraulic power in older imperial units, aiding historical comparisons and legacy system analysis.

Is foot pound-force per hour a standard unit?

No, foot pound-force per hour is a non-SI unit used mainly for small mechanical power rates, often in legacy or specialized engineering contexts.
