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).

## What is the meaning of 1hp motor?

Horsepower, the common unit of power; i.e., the rate at which work is done. In the British Imperial System, one horsepower equals 33,000 foot-pounds of work per minute—that is, **the power necessary to lift a total mass of 33,000 pounds one foot in one minute.**

## What is the power of 1 hp motor?

If the motor is fully loaded, it will provide output power of 1 HP = **(1 X 0.746) kW = 0.746kW**. Electrical Input Power = (Output Power/Efficiency). Assuming 90% efficiency, Input Power = 0.746/0.9 = 0.83kW.

## Is 1 HP equal to a horse?

Calculating the Power of a Single Horse

Each horse pushed with a force that Watt estimated at 180 pounds. From this, Watt calculated that one horsepower was **equivalent to one horse doing 33,000 foot-pounds of work in one minute**. … That amount of work equals one horsepower.

## What does 2hp mean?

It’s **the power of the motor**. A power output of 2 x 746 watt can be delivered by a 2hp motor.

## How is hp calculated?

The equation to calculate horsepower is simple: **Horsepower = Torque x RPM / 5,252.**

## How much does a 1 HP motor cost?

Our 1 hp (standard) example UST1102 motor above will cost **between $1-$5 per day**, depending on what your power company charges per kWh, and on how many hours per day the pump is running, which changes within the season. This will result in a monthly cost of $30-$150.

## How many kW is a 5hp motor?

Since one electric horsepower is equal to **0.746 kilowatts**, the formula to find kilowatts is to multiply electric horsepower by 0.746. For example, here’s how to convert 5 electric horsepower to kilowatts using the formula.

## How much horsepower is considered fast?

Some of the most powerful and fastest cars in America start from **650-horsepower and above**, and one could definitely consider that to be fast. Topping the ranks of fast cars in America include the following: 2020 Chevrolet Camaro ZL1: 650-horsepower. 2021 Dodge Charger and Challenger Hellcat Widebody: 717-horsepower.

## Why is horse power called horsepower?

James Watt, who invented steam engines, figured out a mathematical way to equate horses to engine power. … Thus the term horsepower was invented. **Watt measured the capability of a big horse to pull a load** and found it could pull a weight of 150-pounds while walking at 2.5 miles per hour.
