I probably know more about the horsepower formula than most people here.
HP= torque x rpm/5252
It is a very simple formula
exactly what is so difficult to understand :h
increase torque you increase HP
increase rpm you increase HP
Yet you continue to infer that only torque is important. :h
That makes no sense.
Well, I'll just settle that right now. I most definitely do NOT, DO NOT, want "to infer that ONLY torque is important".
But, obviously I am a big fan of big, low-rpm diesel engines (and their standard design characteristics). And, for the purpose of selecting a diesel engine for DP motorhomes, I only ask to see the torque curve. But, it's because that is all I MYSELF need. Everyone else can use whatever method they think is best for them.
Yes, the horsepower formula is simple (the way you presented it). But, I enjoy knowing how it came to be derived (the history of it).
And, I enjoy converting engine torque into force of propulsion. There's several "basic physics" formulae which incorporate FORCE.
