Transcript of The Steam Engine

The new need for coal to power the steam engines was great. This created more mining jobs. That brings around another use of the engine: pumping water out of mines. This was a long and boring job,
so it was practical to use a machine. The Watts steam engine did the work of 20 horses pumping water. One of the most well known uses of the steam engine is the steam locomotive. It was the fastest form of transportation at the time. It allowed goods to be transported from one place to another in a matter of days instead of weeks, like horses and carriages. People could now travel much faster. The short term impact of
the steam engine As a result of the locomotive, hundreds of farmers were moving into big cities for better work. This helped the economy because there were more people to purchase goods, but jobs were in high demand. Many saw mills used steam engines. Before the invention of steam engines, saw mills used the power of rivers. Now they did not need to be near a river. Many historians and economists have different theories whether the steam engine started the industrial revolution or the industrial revolution inspired the steam engine. Either one could be correct, but certainly the steam engine had a big part in the industrial revolution. Joe Early The Steam Engine The long term impact of the steam engine Steam engines are still around today.
The most common use is to create energy by using a steam turbine. Steam turbines create around 85% of the world's energy. One long term impact of the steam locomotive is that it inspired mass transportation. The steam engine allowed many people to travel far distances in little time. This is still seen in our daily lives today. The steam engine introduced the idea that coal could be used as a power source. It is still being used as a power source today and creating jobs. Modern
Steam Engines The biggest improvement on Watts engine was high pressure steam. Watt never experimented with high pressure steam because he was afraid of an explosion. The original steam engines operated at 15 pounds per square inch (p.s.i.). The first high pressure steam engines operated at 30 p.s.i. in the early 1800s. Today high pressure steam engines operates at more than 1,000 p.s.i. Two other improvements
to steam engines are compound engines and superheated steam. video of a model steam engine A compound engine is an engine
where the steam is expanded in two or more places. This creates a more efficient engine because not as much energy is lost. Steam engines have also inspired many new engines such as combustion motors which are most commonly used in automobiles. The steam engine has forever changed the world. Transportation is now much faster. It has also employed many people. It also played a major role in the Industrial Revolution.
