“Horsepower”, as its name implies, is the power of a horse. So what is the power of the horse? How did it get called “horsepower”?
In 1765, The British Watt invented the world’s first steam engine, from then on, the human entered the “steam age”. The practical application of steam engine was first started in coal mines. A coal mine owner, want to use steam to replace horses to carry water, ordered a steam machine to Watt. In order to design and build such a “mechanical horse”, watt measured the power of a strong horse. The result was that the horse could pull up 70kg of water at 1m/s, that is to say, the horse had a power of 70kg. M /s. And called the power of this steam engine one “horse power”. That’s how horsepower got its name.
The source of “horsepower” is determined according to the horse’s working ability, but the horse’s ability varies from horse to horse. The average horse has only 0.4 to 0.6 horsepower. Now, “horsepower” has become a special term for engine power.
