rolling mill horsepower calculation

rolling mill horsepower calculation

Horsepower is a measure devised by 19th century manufacturers of steam engines (literally engineers ) to compare the work performed by their machines with the amount more traditionally achieved using horses and pit ponies. It was determined that horses of that era could, on average, elevate a weight of 330 lbs. by a height of 100 feet, in a
