Question

What is the Industrial Unit of Power?

Answer 1

Power:

1. Power is defined in physics as the quantity of energy transported or transformed per unit of time.
2. The watt is the unit of power in the International System of Units, equivalent to one joule per second.
3. Power is a scalar.
4. Power can mathematically be expressed as: $P=E/t$ where ‘E’ represents energy and ‘t’ represents time.

Solution:

1. The industrial unit or the imperial unit of power is ‘Horsepower’. It is generally used to rate the engines of automobiles.
2. 1 Horsepower (HW) = 746 Watts (W).
3. In the automobile industry Horsepower is given by the following equation:

$HP=Weightx\frac{Velocit{y}^2}{{234}^2}$, weight and velocity are in their S.I units.

The Industrial Unit / Imperial Unit of power is Horsepower (hp).
