Question

state the relation between horsepower and Watt

Answer 1

The horsepower (hp) is a unit in the foot-pound-second ( fps ) or English system, sometimes used to express the rate at which mechanical energy is expended. It was originally defined as 550 foot-pounds per second (ft-lb/s). A power level of 1 hp is approximately equivalent to 746 watt s (W) or 0.746 kilowatt s (kW).

Answer 2

in SI system the unit of work is j so the unit of power is j/s .
this is called watt.
1 watt = 1 joule / 1 second
in the industrial sector the unit used to measure power is called 'horse power's
1 horse power = 746 watt .
