How many horses were replaced by a steam engine of James Watt?

Question

This is from class 11th history chapter the industrial  revolution 

Answer 1

Watt performed some reverse engineering to determine how many horses would equate to a steam engine in order to communicate the cost efficiency of his product. Watt's horsepower (hp) unit of measurement is based on a horse pulling a twelve-foot mill wheel for four hours. Using the this formula, the maximum output of a horse is around 15 horsepower per day. By 1969, 1200 steam engines had been sold, totalling 118,500 horsepower (approx 99 hp each). 

Therefore, each steam engine replaced about 6.6 horses on average per day.

Answer 2

There is no definitive answer to this question as it is based on estimates and assumptions. However, it is commonly cited that one horse can generate 0.75 horsepower, so Watt's steam engine, which could generate 5-10 horsepower, could potentially replace between 7-13 horses.

Answer 3

There were many horses than were replaced by a steam engine of James Watt. In fact, there are so many that it is Impossible to even list all of them. Some that are replaced by him, are mustangs, horses, and horses are replaced by steam engines in the modern day.

Answer 4

there are so many that it is Impossible to even list all of them. Some that are replaced by him, are mustangs, horses, and horses are replaced by steam engines in the modern day.
