Question

I posted a video today on the need to perform utility rate optimization before evaluating equipment upgrades.  This topic and the video are both informative and provide insight on how not doing so can bite you in you payback analysis.  I thought that this was very applicable content in this section and it was subsequently deleted.  I'd like to know why that would be the case.  I didn't even receive a message to that affect.

The video is not applicable to preparation for the Mechanical PE exam and was subsequently  moved to the General Engineering forum.  

ok ty   Sorry for posting in the wrong spot
