Flow in positive psychology, also known colloquially as being in the zone or locked in, is the mental state in which a person performing some activity is fully immersed in a feeling of energized focus, full involvement, and enjoyment in the process of the activity.
A fluid power system has a pump driven by a prime mover (such as an electric motor or internal combustion engine) that converts mechanical energy into fluid energy, Pressurized fluid is controlled and directed by valves into an actuator device such as a hydraulic cylinder or pneumatic cylinder, to provide linear motion, or a hydraulic motor or pneumatic motor, to provide rotary motion or torque.
Con Edison is now the largest operator of the New York City steam system, which is the largest commercial steam system in the world with more than 100 miles (160 km) of steam pipe. [ citation needed ] It provides steam service to nearly 2,000 customers serving more than 100,000 commercial and residential establishments in Manhattan south of ...
The two-pipe reverse return configuration which is sometimes called 'the three-pipe system' is different from the two-pipe system in the way that water returns to the boiler. In a two-pipe system, once the water has left the first radiator, it returns to the boiler to be reheated, and so with the second and third etc.
Expansion joints on a steam line that have been destroyed by steam hammer. Steam hammer can occur in steam systems when some of the steam condenses into water in a horizontal section of the piping. The steam forcing the liquid water along the pipe forms a "slug" which impacts a valve of pipe fitting, creating a loud hammering noise and high ...
The steam generated pressurized the container, but the inner pipe, immersed at the bottom by liquid, and lacking an airtight seal at top, remained at a lower pressure; expanding steam forced the water at the bottom of the container into and up the pipe to spurt out of a nozzle on top. These devices had limited effectiveness but illustrated the ...
In a steam engine, cutoff is the point in the piston stroke at which the inlet valve is closed. On a steam locomotive, the cutoff is controlled by the reversing gear.. The point at which the inlet valve closes and stops the entry of steam into the cylinder from the boiler plays a crucial role in the control of a steam engine.
Steam engines of this kind propelled the Industrial Revolution in Great Britain and the world. The Watt steam engine design was an invention of James Watt that became synonymous with steam engines during the Industrial Revolution, and it was many years before significantly new designs began to replace the basic Watt design.
