percentage efficiency Explanation: Alternative 1: percentage efficiency (relative to an ideal cooling apparatus). Alternative 2: percentage efficiency (relative to a 100% efficient cooling apparatus). Alternative 3: percentage efficiency (relative to a zero-loss cooling apparatus). (Note: I am a professional thermodynamics engineer.) -------------------------------------------------- Note added at 3 hrs (2020-04-14 18:35:49 GMT) -------------------------------------------------- Reference: large.stanford.edu › courses › wolkoff1 › docs › power_generation_f... Power Generation from Coal ... a lower heat rate is more efficient and gives a higher percentage efficiency. |

efficiency factor Explanation: Der Wirkungsgrad beschreibt die Effizienz einer technischen Einrichtung oder Anlage als dimensionslose Verhältniszahl oder Prozentsatz, und zwar in der Regel das Verhältnis der Nutzenergie Eab zur zugeführten Energie Ezu. : Pab ist beispielsweise die mechanische Leistung, die ein Elektromotor an der Welle abgibt und Pzu die elektrische Leistung, die dem Motor zugeführt wird. Der Gütegrad beschreibt hingegen nur innere Verluste einer Maschine und fällt meist erheblich besser aus. https://de.wikipedia.org/wiki/Wirkungsgrad Der Gütegrad ν (gr. ny) ist ein Maß für die inneren Verluste einer Maschine und gibt an, wie weit ein realer thermodynamischer Prozess an den theoretischen idealen Vergleichsprozess (z. B. Carnot-Prozess, Joule-Prozess) einer Maschine angenähert ist: : Der Gütegrad wird häufig mit dem Wirkungsgrad verwechselt. Der Unterschied besteht darin, dass (vgl. Formel oben): • ein Wirkungsgrad jeweils das Verhältnis von genutzter (abgeführter) zu eingesetzter (zugeführter) Leistung bzw. Energie angibt; Wirkungsgrade können für den realen und für den idealen Prozess gebildet werden; • der Gütegrad das Verhältnis von real genutzter zu idealerweise genutzter Leistung angibt; der Gütegrad setzt daher die beiden Wirkungsgrade von realem und idealem Prozess ins Verhältnis. https://de.wikipedia.org/wiki/Gütegrad efficiency factor [TECH.] der Gütegrad Pl.: die Gütegrade efficiency rating [TECH.] der Gütegrad Pl.: die Gütegrade performance factor of the airscrew [TECH.] der Gütegrad Pl.: die Gütegrade https://dict.leo.org/englisch-deutsch/Gütegrad DE: Der Gütegrad vergleicht den Kreisprozess des realen Motors mit dem idealen Kreisprozess des entsprechenden Motors.

(Technological Dictionary: Volume II English — German — French) The efficiency factor is included to account for the actual performance of the turbine as opposed to the ideal, isentropic performance. In an ideal world, the value of the efficiency would be 1.0. In reality, it is always less than 1.0. Because of mechanical inefficiencies, you cannot get 100% of the available work from the turbine. https://www.grc.nasa.gov/WWW/K-12/airplane/powtrbth.html Efficiency We can compare the amount of work required in an irreversible process to that of a reversible process by defining the efficiency factor... https://books.google.de/books?id=wqdsDwAAQBAJ&pg=PA55&lpg=PA... (Engineering and Chemical Thermodynamics) The Carnot method is an allocation procedure for dividing up fuel input (primary energy, end energy) in joint production processes that generate two or more energy products in one process (e.g. cogeneration or trigeneration). … For heat this potential can be assessed the Carnot efficiency. https://en.wikipedia.org/wiki/Carnot_method Figure 2: Carnot cycle efficiency with changing heat addition temperature. Figure 3: Carnot cycle efficiency with changing heat rejection temperature. https://en.wikipedia.org/wiki/Heat_engine#Efficiency In general, energy conversion efficiency is the ratio between the useful output of a device and the input, in energy terms. https://en.wikipedia.org/wiki/Thermal_efficiency |
