I am having a hard time with the concept of mechanical work not showing up as heat. Motion doesn't generate heat? That pump pushing water up 30 meters is consuming x watts but is not generating the same x wattage as heat? That sounds contradictory to post #2 by Nugarory, which is in line with...
Does that pump not consume wattage and that wattage consumed converted into heat? Both a 100 watt submersible pump and a 100 watt electrical heater consume and release heat back to the water as 100 watts. Even the work being performed by the pump, moving water, creates friction which also...
That was the question Russ. I have never been a believer in absolutes. I had a feeling it was possible to use wattage that did not result in a heat exchange but could not think of any examples. I am here to learn and that is my only absolute. I still don't know of any examples or understand...
Thank you, and yes I do understand that in "real world" scenarios there may be a fraction lost but somewhere along the journey to Andromeda it will give off it's energy as heat.
Phillip it is my understanding that no matter what form the energy is converted to, the result will be heat, no...
Gentleman, I appreciate the confirmation. College was a long time ago but the learning has yet to cease. Sadly the older we get the more our brains resemble a wiffle ball.
In essence, wattage consumed will eventually be returned as heat, in the same amount as the wattage drawn. 100 watts of...
First post here, so much to learn -- About Heat & Power
I would first like to thank those who participate on this forum, I have referred to it several times in the past and have found it highly informative.
I am not a teacher, just an old man intrigued by learning, I am mostly retired and...
