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.
