Solution

Horsepower ( $H P$ )
The two different units of power are horsepower and Watts. Power can be electric or mechanical, and it can be converted back and forth.
Home appliances and many industrial appliances use this unit of power for rating electric appliances. The submersible pumps, well pumps, and other motors have power ratings given in $H P$ .
Generally, we use the motors from $1 H P t o 10 H P$ . Therefore, $H P$ is the practical unit of power.
Prove that $1 H P = 746 W$
$1 H P = 550 F o o t P o u n d p e r s e c o n d 1 H P = 550 * 4.44822 * 0.3048 m e t e r s [a s 1 P o u n d = 4.44822 m e t e r s, 1 F o o t = 0.3408 m e t e r s] 1 H P = 745.69 N m / s 1 H P = 746 W a t t s .$
Hence, proved $1 H P = 746 W$
