Now you are getting it, you can see the problem I am dealing with. The people that I am speaking with are not experts in this area, one is from power plant support engineering, the other is a "rain-maker" for a company.
Thank you all for all of your suggestions on how to explain my situation to other engineers in the company. I will take what has been posted and think about how to have that discussion.
IRstuff, that is a good idea, see attached screen shot as an example.

Okay, so what do you call the power available to any system? What do you call the power required to operate any system? As mentioned earlier in this thread, Greenheck on their spec sheets have HP and Operating HP. My understanding of this is one term tells me the motor size, and the other...
Compositepro,
I find your discussion interesting. However, when the other engineers I talk to are unwilling to discuss it, and simply say parenthetically; this is not a discussion. The electrical engineer that I work with has very little understanding of this topic. As for the difference...
I want to thank all of you who replied to my question. I did not expect such a variety of responses.
What I am hearing is that the difference is more or less moot because of the variety of contexts in which these terms are used.
This all started when one of my engineers used BHP on a drawing...
This conversation sounds like there is no one answer, it sounds like the context of usage defines the meaning. That said, we specify a lot of fans for various systems and Greenheck when you use their sizing program the cut sheet for the given fan has two fields for horsepower; operating...
It is not about the units of measurement.
Maybe I made the question too complicated. Other engineers in my company are saying that BHP is the power to operate the system, and that HP is the nominal or motor size. And I do not agree. The context is for electrical motors that are driving a...
I seem to be the only one in my company that believes that BHP is the power available to the system before losses due to appurtenances, e.g. a belt drive for a fan. For simplicity sake,(I may not be using an accurate analogy) I suggest that the BHP is the NEMA or nominal horsepower. For...
