What does one foot pound-force per second represent?

It is an imperial unit of power equal to one pound-force acting over a one-foot displacement each second, used to express mechanical power.

When should I use horsepower (water) instead of mechanical horsepower?

Horsepower (water) is used to estimate hydraulic power for moving water against a head, important in pump and turbine design.

Can the converted values be affected by real-world system inefficiencies?

Yes, the water horsepower calculation assumes ideal conditions; actual hydraulic power can be lower due to losses.
