Paladin,
You've getting close but your not there yet. If we are using the same prop, driven by the same engine, at the same RPM's under normal conditions without cavitation; then why does cavitation happen to the system in foul weather? I think that, just maybe, you are about to learn something; along with some others(g) The graph will show it, if you you can figure it out. THINK FIRST and then prove you thought with the graph. Again I'll say Bye, Bye and I'm sorry I didn't keep my word and stay out of the discussion http://community.webtv.net/tassail/ThomPage |

Can't Help It Paladin,
If you're so Damn Smart, why are you rambling on about language and boiling under the heading of: "USELESS PROPELLER!" That's stupid! http://community.webtv.net/tassail/ThomPage |

That's stupid! You and most others here demonstrate shallowness of thinking. What's stupid is to expect to even attempt to discuss the utility or uselessness of propellers if folks are speaking different languages. And, mark my word, unless folks can agree on word definitions they are speaking different languages. 1) The discussion media here is the written word. 2) Written words have specific and agreed upon meanings. 3) Unless those meanings are understood clearly by all concerned discussion is confusing and meaningless. 4) I'm "rambling on about language and boiling" because the entire thread went the wrong direction because of confusion about the meaning of words. 5) The only way to get things back on track is to agree on commonly accepted definitions of the word "boil" in this case. 6) The only way to keep things on track in the future is by continually pointing out that people must use words as defined and NOT as they, in their imagination, think words are defined. 7) If a person as intelligent, well-versed, educated, and logical as Gilligan is confused about the meaning of certain words just how lacking is the understanding of the average subscriber here who lacks education beyond the 8th grade level. 8) Why should those of with Masters and Doctorates lower ourselves the level of 8th graders. Isn't it more productive to attempt to raise 8th grader understanding to at least a high school graduate level? If you'll recall Gilligan's original reply it stated something to the effect that cavitation happens because the prop boils the water. I say any prop that boils water is useless as a prop but handy as a water heater for showers and such. Therefore such a prop is useless for moving a yacht and, as such, discussing it under the heading of "Useless propeller" is entirely correct.

He visited the fine state of Colorado last month. No one, not even Paladin, can be as brilliant as the good Capt, though Simple Simon came close. |

Two devices for transferring energy, surely they can both be said to "boil" things. Fresh Breezes- Doug King |

Your thinking that's what I'm doing is just plain dumber... One boils water by adding heat. One doesn't boil water by reducing pressure. The verb "to boil" simply does not apply to the vaporization of water by reducing pressure. It follows that any process that vaporizes water by heating it can correctly be said to be boiling the water. Any process that vaporizes water by lowering pressure cannot be said to be boiling water by definition. It can only be said that lowering pressure vaporizes water. | | Here is a dictionary that defines "boil" perfectly, at least | with regard to you personally: | http://www.medterms.com/script/main/...rticlekey=2498 Duh? Too dumb to differentiate between a noun and a verb?

They are adding heat only so they are boiling it. The lower atmospheric pressure only means they are able to boil water usling fewer BTUs because the boiling point temp is lowered. | | A stove is a device for transferring energy from an outside | source into the food.

The definition of the verb "to boil" precludes it. Paladin -- Posted via a free Usenet account from http://www.teranews.com |

In fact in a vacuum water's | boiling point and freezing point are the same. It's called being at | "triple point". It's how thermometers are calibrated as a matter of | fact. The definition of boiling in English states that it's a process induced by adding heat. It says nothing about reducing pressure. To claim you can make water boil by reducing pressure is erroneous. (where's the application of heat?) You can only vaporize water by reducing pressure. You can't boil water by reducing pressure. Saying "I'm gonna boil this water by reducing pressure" is like saying, "I'm gonna drink this beer by putting it up my ass via enema." Just as the verb "to drink" means to ingest via the mouth and esophagus so does the verb "to boil" mean vaporize by adding heat. | | Honestly, this is 7th grade general science in MOST school districts. | Which tells us you not nearly as "brilliant" as you believe you are. ![]() | And, your lack of understanding of a simple word definition and its implications means you're lacking insight.
