What does 1 horsepower (550 ft*lbf/s) represent?

It is an imperial unit of mechanical power equivalent to 550 foot-pound-force per second, commonly used to rate small engines and machinery.

Why convert horsepower to Btu (th)/hour?

Converting mechanical power in horsepower to thermal power units like Btu (th)/hour helps compare engine outputs with heating and cooling system requirements.

Is this conversion suitable for dynamic power conditions?

No, the conversion assumes steady-state power and does not consider transient effects or efficiency during mechanical to thermal energy conversion.
