«*» RUKHSANA«*» Is Horsepower Measured Using Horses?

 

Almost everyone has heard of horsepower – Most lawn mowers come with horsepower ratings, and the power of car engines are commonly gauged in horsepower… but when asked what it is, most would shrug and say they don't know! So what is it? Horsepower was invented by engineer James Watt (it's thanks to this guy we have the light bulb measured in "watts"). Watt has made his name is history especially because of his work on steam engines, and invented the term horsepower which is widely used to measure the output of piston engines, turbines, electric motors, and other machinery. One horsepower unit ranges between 735.5 and 750 Watts (depending on whether the horsepower is mechanical, electrical, or metric) Here's how the story goes – Once upon a time when Watt was working with ponies lifting coal at a coal mine, he wanted to have a form of measurement which would determine the power of the animal. Watt determined that a pony could do an average 22,000 foot-pounds of work per minute over a four-hour working shift. Watt then judged a horse was 50% more powerful than a pony and thus arrived at the 33,000 foot-pounds figure, which equals to 745 Watts. It is this figure which we see on our lawn mowers, cars, and even your vacuum cleaner sometimes!                     WARM REGARDS, Akhtar khatri *****help what we can with others in need...the world is ONE big family*****   ALL THE MAILS POSTED BY ME R NOT MY PROPERTY, ALL R TAKEN FROM NET, IF SOMETHING IS COPYRIGHTED PLZ INFORM ME, SO THAT I MAY NOT POST THE MATERIAL IN THE FUTURE
