Which creates more heat?

[Bluerubi]

Agreed. It is those gut feelings that demand so much conviction.

Even though I get my wood for free, I am all about heat to the room. It still is a lot of work to get wood from the forest up to my doorstep.

This reminds me of an interesting engineering problem.

A guy is out on a lake in a rowboat. He drops the anchor out of the boat onto the bottom of the lake. Does the depth of the water in the lake go up/down/ stay the same?

This is not a trick question. There is one correct answer.

MnDave

I think the key to your question is the comment about it sinking to the bottom. For that to happen the anchor material needs to be more dense than water, so it should displace more water sitting in a boat then when it sits on the bottom. Therefore, my vote is level will go down.

 

[MnDave]

Lastly a concept to throw out there is the one reason these stoves are efficient is since you can build the heat in the fire box you can reduce the air flow really low and still keep the secondaries burning and the reduced air input is slowing the amount of heat flushing up the flue.

Totally agreed.

Efficiency in this case being the heat value in the wood that ends up in the room/house vs up the chimney.

Those secondary burn tubes or cats (let's not forget the other religion) are key to efficiency.

Based on what I have read, cats do a better job of controlling the burn process at optimum. Fortunately the EPA cared mainly about emissions. If they were also driving mfgs by efficiency, (like CAFE standards on cars) tube stoves might not be on the market, as they are probably less efficient unless controlled by a microprocessor.

That said, a great tube stove operator (Huntindog1) will get more out of their non-cat stove than a cat stove operator who is confused about cat operation.

Bingo.

A coworker told me that he interviewed at 3M before choosing IBM. The interviewer asked him this question point-blank. I think he had a masters degree so that was fair game. Right?

[HotCoals]

No guessing Hot Coals. lol

Here is a hint/lead. The anchor is of course made of steel.

BTW I think that you have the most awesome stove I can imagine. Are there heat shields on that?

MnDave

Thanks and no I don't have the heat shields.
That pic was before it was even fired up.

That ain't much of a hint for a redneck wanabe thermodynamics engineer! lol

Labatt's beer is the best..but I drink Captain Morgen/Coke!

...what is the airspeed velocity of an unladen swallow?

No surprise on the heat shields.

That was a lead. I should have stalled the answer a little more. Truth be told. I did not get it, my good friend and neighbor, who is also a layed-off IBMer solved it verbally in about 2 minutes. Read what bluerubi wrote best explanation takes the fewest words.

I love Labatt's but cannot afford it until Social Security kicks in. J/k I am a cheap SOB.

Captain Morgens/coke... I love it but it keeps me up all night... sometimes a good thing if ya know what I mean.

I mainly drink Busch Lite. Less than $15 a case.

I cannot imagine having as many post as some of the folks on this forum. But this a really nice place.

I like Martini's too.

roughly 11 meters per second

just a rough quess but almost intuitive

Yep ..I seen his answer after I posted.
I knew the weight of the anchor in the boat had something to do with it!
I should have realized the anchor would not displace water no where as much in the water as it did in the boat..dang.

You can get addicted to this place..fine people for sure!
I hang here and at a snow sled site a lot in the winter...actually the sled site all year..lol.

Yep when I heard the logic I thought, duh. I thew away the ruler I was so pissed.

Sleds. Got 4. Two 600's, 2 older 440's. Fun. My wife rides.

Don't want to hijack. Which sled-site? Who are you there?

The water level neither rises nor drops...




...It's a dry lakebed due to extreme drought conditions.

Awe, why did you have to bring up glow ball warning?

An African or European swallow?

 

[Tramontana]

...um...

I didn't, you did?


I'm answering from a western USA perspective where we've been experiencing record drought conditions, that and the written problem states the anchor is dropped from the boat "onto" the bottom of the lake rather than "into" the lake.


Cheers!

I might have a sign-on there. Not sure. Seemed king of intimidating for newbies. I wrench on older sleds mainly.

A Yami, I have an 81 SS 440. A screamer... Probably the fastest 440 and the most 440's still on the trail.

I'll check out hardcoresledder Capt.

Waring..we are out there on that site..check for me in the general forum.
Is that a srx 440?

Ok math guys..figure this.

A 10 foot rope ladder hangs over the side of a boat with the bottom rung on the surface of the water. The rungs are one foot apart, and the tide goes up at the rate of 6 inches per hour. How long will it be until three rungs are covered?

Not a SRX 440. Just a run-of-the mill SS 440. I wanted a SRV 540 soooo bad. But sofar the ones I have checked on have sloopy steering. Dang... they had too much fun with those machines.

Can I get back to you on that stumper, I need some mainframe computer time to crunch that one... gravitational effects and all.

Is the boat aground or afloat?

If she is aground, there is not enough information. If she is afloat, the waterline of the incoming tide should not ever wet any additional rungs as the top of the ladder over the side of the boat will rise equally as the boat rises with the tide.

Cheers!

I believe the answer to you question depends on which one of the fate of universe theories (heat death, heat death without proton decay, big crunch, etc) proves to be true. no?
