Maximum Efficiency

Some articles on efficiency, maximum efficiency:

Carnot Cycle - Properties and Significance - Carnot's Theorem
... any cycle operating between temperatures and, none can exceed the efficiency of a Carnot cycle ... Thus, Equation 3 gives the maximum efficiency possible for any engine using the corresponding temperatures ... Namely that the theoretical maximum efficiency of a heat engine equals the difference in temperature between the hot and cold reservoir divided by the absolute temperature of the hot reservoir ...
Helix Angle - Applications - Screw
... The maximum efficiency for a screw is defined by the following equations Where is the helix angle, is the friction angle, and is the maximum efficiency ... of the screw and interacting nut, but ultimately the efficiency is controlled by the helix angle ... The efficiency can be plotted versus the helix angle for a constant friction, as shown in the diagram to the right ...
Nicolas Léonard Sadi Carnot - Reflections On The Motive Power of Fire - The Carnot Cycle
... He showed that the efficiency of this idealized engine is a function only of the two temperatures of the reservoirs between which it operates ... be eliminated if the heat engine is to achieve maximum efficiency ... Regarding the second point, he also was quite certain that the maximum efficiency attainable did not depend upon the exact nature of the working fluid ...

Famous quotes containing the words efficiency and/or maximum:

    Nothing comes to pass in nature, which can be set down to a flaw therein; for nature is always the same and everywhere one and the same in her efficiency and power of action; that is, nature’s laws and ordinances whereby all things come to pass and change from one form to another, are everywhere and always; so that there should be one and the same method of understanding the nature of all things whatsoever, namely, through nature’s universal laws and rules.
    Baruch (Benedict)

    I had a quick grasp of the secret to sanity—it had become the ability to hold the maximum of impossible combinations in one’s mind.
    Norman Mailer (b. 1923)
