Should the information on this page be moved to Gas turbine?? Pud 8 June 04, 8:58 PST
[edit] Efficiency
Some typical and maximum efficiency levels would be useful. Tobyw 12:12, 8 March 2006 (UTC)
[edit] Ideal Brayton Cycle
It's been a little while since my Heat Transfer and Thermal Fluid Systems classes, but I think that "compression ratio" is incorrect. "Pressure ratio," which is used in most of this article, is the correct term. Compression ratio is a ratio of volumes, while pressure ratio is a ratio of pressures. I don't have my books handy to confirm this, but hopefully someone will take a look at this and make the correction if necessary.
[edit] The illustration
If I am not completely mistaken, the work output of the turbine is proportional to the area that is enclosed by the cycle diagrams. Consequently, the enclosed areas in both cycles diagrams should be of the same size. If this statement is correct, I think it will be nice to visualize this in the figure, e.g. by shading those areas and writing "W" or "Work out" into them.
Another issue: Does anyone know, whether the diagrams can also be used to derive a statement with respect to the efficiency of the turbine?Tomeasy (talk) 14:40, 6 December 2007 (UTC)
