USA HISTORY

Detailed explanation-1: -A steam engine converts heat into mechanical work. It was the first machine to do so. It is actually a heat engine that performs mechanical work using steam as its working fluid.

Detailed explanation-2: -A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force is transformed, by a connecting rod and flywheel, into rotational force for work.

Detailed explanation-3: -In about 1712 another Englishman, Thomas Newcomen, developed a more efficient steam engine with a piston separating the condensing steam from the water. In 1765 James Watt greatly improved the Newcomen engine by adding a separate condenser to avoid heating and cooling the cylinder with each stroke.

Detailed explanation-4: -Watt went on to further refine his revolutionary design, so that Boulton & Watt steam engines could not only efficiently pump water, but drive machinery in paper, cotton, flour and iron mills, textile factories, distilleries, canals, waterworks and even drive an early steam locomotive.

Detailed explanation-5: -Watt introduced a design enhancement, the separate condenser, which avoided this waste of energy and radically improved the power, efficiency, and cost-effectiveness of steam engines. Eventually, he adapted his engine to produce rotary motion, greatly broadening its use beyond pumping water.
