Please forgive if the information I'm asking for is hidden somewhere in the links this thread generated. That's part of my problem: searching yields too many hits and none have panned out for me, so far.
I am looking for a table containing (average) energy conversion rate values, for such things as internal combustion engines, steam turbines, diesel generators, and in general, energy conversion equipment. I don't need this for a specific machine, just ballpark figures. Can someone point me at such a table? I think I have found many of the more general resource sites on the net and while some provide some of the information I am looking for, I have not found everything I need. Help will be much appreciated.
