Steam Turbine Generators II

Today I was mindful of another fluid mechanics law that takes place inside a steam turbine generator. The inside of a steam turbine is composed of a series of nozzles and metallic fans. The nozzles take the low velocity, high pressure fluid (usually steam) and introduces a pressure drop which converts some of the fluids energy, which is stored in the steam's high pressure, into kinetic energy. Converting the energy stored in pressure to kinetic energy results in the steam having an extremely high velocity. The high velocity steam hits the metallic blades of the interior fans and transfers kinetic energy and momentum to turn the blades. The steam is then recollected and recycled. The recycled steam then goes through another series of nozzles and fans until most of the energy stored in the steam is extracted. A turbine's efficiency is based on how much energy it can extract from the high pressure steam entering the turbine. An efficient turbine will have an exit pressure close to atmospheric pressure.
