I can get the books out if anyone wants to get specific, but HP is the ability to move a mass a distance in a period of time. HP is HP. It comes in any form that can convert energy (any type of available energy) to "energy consumed at some rate"...hence work...hence watts(electrically speaking) hence PTO HP (mechanically).

The differences really are what floats your boat. If you have an X HP (dyno'd) PTO and an X HP electric motor initially, you have equivalent methods of consuming energy and producing work. You can adapt whichever you prefer.

The difference is primarily efficiency of the process and for you, convenience. There are losses in all delivery sytems and if you balance out your losses with more HP as required, you will get the same amount of work done.

Pipe resistance is a constant and doesn't care what is blowing whatever is being blown down it. It does care what and how fast but that is a constant in answer to your question.

Want more ask.
