Part one of term paper
The invention of the water turbine was so successful that eventually, the idea came about for extracting power from steam. Steam has one great advantage over water-it expands in volume with tremendous velocity. To be the most effective, a steam turbine must run at a very high speed. No wheel made can revolve at any speed approaching the ve ...

... is based on the thermodynamic principle that when a vapor is allowed to expand, its temperature drops. In turn, its internal energy is decreased. This reduction in internal energy is transformed into mechanical energy in the form of an acceleration of the particles of vapor. The transformation that occurs, provides a large amount of available work energy. The essential parts of all steam turbines consist of nozzles or jets through which the steam can flow and expand. Thus, the temperature d ...
