Hello again friends,
<div class=""><br class="">
</div>
<div class="">I don’t wish to prolong the efficiency discussion of which so many are weary. I would just like to ask for help with information. Anyone who wishes to go away from this topic, I completely understand. You may immediately delete this message. </div>
<div class=""><br class="">
</div>
<div class="">Let us suppose that we have ANY device that does two things: giving heat and light, refrigerating food and making ice, producing heat and electricity, producing cooking heat and char. </div>
<div class=""><br class="">
</div>
<div class="">**If you know of ANY example in engineering practice, OTHER than the WBT, in which the efficiency is calculated by subtracting one of the services from the denominator rather than by putting both outputs in the numerator, can you please make it
known to me?** </div>
<div class=""><br class="">
</div>
<div class="">This is not a question of devaluing any of the device’s outputs— I am seeking only the appropriate method of communicating them. </div>
<div class=""><br class="">
</div>
<div class="">Within TC285 - WG1 (“Conceptual Framework”), I am seeking support via precedent, for what you folks have been calling the “denominator equation" of calculating efficiency. I have done a search of the engineering literature to find such an precedent,
and I cannot find one. The lone exception is use of byproduct gas from cokemaking, and there we have a difference in the control volume, where in the cokemaking situation one can draw a proper control volume around the byproduct boiler. </div>
<div class=""><br class="">
</div>
<div class="">I don’t think we need more discussion about validity of equations. I am looking only for precedents other than the case at hand. I would like to have references or links if at all possible. </div>
<div class=""><br class="">
</div>
<div class="">I am not seeking to prolong the discussion in WG1, either. I am hoping to close it down. If anyone is able to help in this search, I will use the information you provide by listing the precedent in a summary of issues which we plan to send to
the group soon. </div>
<div class=""><br class="">
</div>
<div class="">
<div class="">I do consider the potential for misrepresentation to stakeholders to be a sufficient and, indeed, a necessary cause for examination of metrics. I also consider it wise for this relatively new community (I mean new in comparison with a couple hundred
years of engineering records) to remain as consistent as possible with previous practice. I recognize that there is a lot of knowledge within the list here and I think that perhaps somebody may be aware of something that I have missed. </div>
<div class=""><br class="">
</div>
</div>
<div class="">Thank you. </div>
