Stupid hp to thrust question

Does a prop turning at 2300 rpm on a 150hp motor produce more thrust than a
prop spinning 2300 rpm on a 100 hp motor ?

+++++++++++++++++++++

Theoretically speaking -

If the props are identical....
so is the thrust on the test stand.

If I'm wrong, never mind.

Assuming both engines are producing the same torque at that rpm, then yes.
Torque x RPM = horsepower. Note: the props will not be both the same
diameter and pitch.

To paraphrase the question...

If I put 150 lbs of crap in a 100 lb bag, and 150 lbs of crap in a 150
lb bag, which bag is holding more crap?

OOooooooo..... *SO* close, and yet just off. I think you meant to say:
"If I put 100 lbs of crap in a 100 lb bag, and 100 lbs of crap in a 150 lb bag,
which bag holds more crap?"

That's an easy one - A 150 lb (capacity) bag holds more crap than a 100 lb
(capacity) bag.

I think YOU meant to say, "If I put 100 lbs of crap in a 100 lb bag, and 100
lbs of crap in a 150 lb bag, Which bag contains more crap?"

Not so fast. If my eyes aren't deceiving me, the only change you made was
"contains" for "holds". English being an exceptionally slippery language, it
seems to me that those terms are synonymous. Makes it rather hard to give a
definitive answer to the original poster's question if we aren't clear on
whether "hold/contains" means "at the moment" or "at maximum capacity", which I
believe is the issue that nafod40 was attempting to illustrate with his
posting. I was only trying to show that nafod40's choice of numbers weren't
quite parallel to the original poster's question.

BTW, there's entirely too much crap in here. :-)

ob. aviation content: My Dad used to drop blivets from the B-52 he flew. :-)

My language was carefully chosen with the utmost attention to detail. To
paraphrase Humpty-Dumpty...

"When I use a phrase," Humpty Dumpty said, in rather a scornful tone,
"it means just what I choose it to mean—neither more nor less."

"The question is, " said Alice, "whether you can make words mean so many
different things."

"The question is," said Humpty Dumpty. "which is to be master—that's all."

I'm sure NO ONE here, not even the crotchety old fool himself, will deny that BOb
is full of crap (sometimes), *BUT* it was nafod40 whom you (Bob Reed) quoted and
not BOb.
