Question

How many horse powers does 746 Watts consist of?

Answer 1

The horsepower is a unit of power. It has some relation with the SI unit of power – Watt. We need to find the relation and solve to find the number of horse powers constituted by the given amount of Watts. The given value of power is 746 Watts.

Complete step by step answer:
The horse power (hp) is the unit of power which is widely used in the commercial field. We are well aware of the use of the term horsepower in describing the powers of a motor used for pumping water from wells, cutting grass or sawing blades. Horse power is, therefore, an important unit of power.
Theoretically, one horse power is defined as almost 746 Watt in standard calculations. It derived its name from the following context: One horsepower is the amount of power used by a horse to lift a 550 pounds heavy object from a depth of 1 foot in one second. This power when converted to SI system gives 746 Watts.
We are given power in units of Watts. We need to apply this relation to find its equivalent value in horsepower.
We know that one horsepower equals 746 Watts.
i.e.,
$1hp=746W$
The given value of the power to be converted to horsepower is also 746Watts.
$\Rightarrow \text{ 746W}\equiv \text{1hp}$
Therefore, the required answer is 1hp.

Note:
We use mechanical horse power widely instead of the metric system. The metric system has a horse power defined a bit lesser than the imperial system. In the metric system, one horsepower is the power used by a horse to lift 75kg of object from 1m depth and it equals 735W.
There is slight variation in the value in mechanical horsepower and metric horse power.
