Re: Consider it done

Excuse me your honour, I would like to point that, while at no time did I mention the work Heinz during the test, the said makers name can clearly be seen on the label in at least two of the pictures. I therefore plead "not Guilty"

Someone else claimed beans floated - I think - so did O concede a point that I should not have conceded? Or am I becoming confused?

[/ QUOTE ]Geez, maybe I'm also getting confused a bit.
Btw, I usually prefer the "threaded" to the "flat" visualization, but in threads like this the indentation becomes hardly understandable... I'll post a question on that somewhere.
Anyhow, my understanding here was that you replied to neale who said "Chuck some beans in the water and they sink", hence I guessed that you wanted to concede him a negative buoyacy, in this case.

But for your and other forumites' peace of mind, my soon to be announced device will be effective with beans and mushy peas as well! /forums/images/graemlins/cool.gif
 
Re: Consider it done

There you go again, you do some half baked (bean) test, using different materials to the original and when you are found out you have the audacity to cry foul and point the finger at somebody else.
Come on now, stop being a silly old silly and admit that you made a mistake and you've bean found out.
 
Re: Consider it done

OK,OK, Ok ........ I have no choice but to agree that Neale did show the tin of Heinz beans in the review. That is a fact. Being a fair man I think it could be reasonably assumed that nobody used photoshop to change itf rom Asda private brand to Hienz ..... I accept Heiz beans were used in the MBM test.

HOWEVER
I have just taken a tin of Heinz baked beans weighing 500 grams on my calibrated scales and measuring7.6cms diameter by 10.5 cms lon = 427.5 cc
Thus giving an SG of 1.17 as opposed to the mushy peas with an SG of 1.08 - so yea baked beans have now been proven to be denser than mushy peas very few people know that, not even Micheal Caine)

This means I have to modify my points - WB with a 1 kg capacity should be able to about 6 kilo of baked beans = 12 (50 gram)full size tins.

So now Neale for test number 2 please use 12 tins of Pull tab Baked beans Henz beans weight 415 grams Tin weight 85 grams.

Satsified?

I did declare my density tests were carried out on mushy peas and I did declare the assumption that mushy peas were the same density as baked beans. In fact I have been accsued of mentioning lead, which i did not and then accused of not mentioning mushy peas which i did. - it a very unjust world.

Its seems to me that Neale has placed to much weight on his baked beans and this fact when combined with the other fact - it took 15 minutes to surface can only lead to one conclusion and that sir is based upon what everyone know what happens to baked beans after a time - they generate gas!!!

Mind you mushy peas have also been know to generate gas but not as much. I mean a film (Blazing Saddles) has been made about the properties of baked beans but not one film to date about mushy peas (unless someone knows better). So it could be my assumption needs to be tested but this time I have to determine the SG of the beans after they have beanz immersed in water for 15 minutes.

No matter what now, after this long thread I shall never be able to look at the mushy peas on my plate without my mind drifting off to water boy and his antics. In a way this will spoil my consumption of this favourite food item purchased from Asda at only 9 pence per tin!!!

I dare say that if Neal should ever receive some new WB's in his hands, he will set about his testing with shaking hands and consdierable care knowing just how much every word he writes will be digested and analysed. /forums/images/graemlins/smile.gif /forums/images/graemlins/smile.gif /forums/images/graemlins/smile.gif

Michael Caine and Gludy\'s dodgy maths

Gludy your maths is all bollox mate. The reason "Michael Caine doesn't know that baked beans are denser than mushy peas" is that they aren't. See below

I have only just latched onto these two threads. Hilarious, fantastic job! Jeeze! A bloke does a demo with a big cube with "1KG" written on it and then comes on here and says it was 3.2KG (duh!!!) then complains when someone says (correctly) he wasn't being fair/truthful in describing the performance of his product! You couldn't make this up!

Gludy is absolutely 100% right with his archimedes analysis. Strange that there were other theories from boaters. As Gludy said (about 9000 times, or er was it about 20? Never mind...) you should measure the "floatation power" of a WB or any other floaty gadget in units of force, ie Newtons. You should aboslotely not measure it in terms of the weight of the item you wish to float. Weight is merely one of the forces acting on the sinking object, namely the force exerted on it by gravity.

If "Newtons" is too scientific, then KGf (kilograms of force) will do I suppose. But look at the labels in your lifejackets - they are all rated in Newtons

Anyway back to Gludy's crappo maths :-). A tin of Heinz beans 7.6cm dia and 10.5cm long is 476cc, not 427.5cc (Gludy, I'm telling you how to suck eggs I know, but it is 3.8squared x Pi 3.1415926 x 10.5 = 476)

A 476cc item weighing 500g has a specific grsavity of 1.05, which means the thing almost floats on its own, especially in salt water. Actually this proves that Gludy's mushy peas approxiamtion (SG 1.08) was pretty damn good and for these purposes is fully validated imho :-)

This makes me seriously doubt Neale's observation. He said a spanner (slender, little drag, SG of about 8) sank at the same speed as a can of Heinz beans (SG 1.05 and much more drag than a spanner). I find that very hard to believe :-)

Anyway, well done with the mushy peas Gludy, and you didn't need to go out and buy a can of beans

What this proves is that there is more to how an object sinks than just its SG. FYI when a spanner hits the water it doesn't go straight down as you would expect, due to the hydrodynamics (of Halfords spanners anyway) it actually "flies" through the water. I dropped one in one meter of water and it ended up about 1.5 mtrs away from the pontoon. That's a flying ratio of 1.5:1 and a vertical drop rate of much less than you would imagine.

Have you tried dropping a tin into water, I can assure you it doesn't almost float, but sinks quicker than an X Factor evictee.

Therfore I have to seriously doubt your figures.
 
Re: Consider it done

I dunno SWMBO has made me put chrimbo decorations up before the kids get home. I come on here whilst she is giving me a well deserved 5 minute break and i've been roped into a poll.

SWMBO driving me up the pole and Gludy adding me 2 one.

I think the culprit for dragging these posts down the route they have taken knows perfectly well whose responsible. /forums/images/graemlins/wink.gif
 
Re: Michael Caine and Gludy\'s dodgy maths

JFM
Sorry the tin was 7.2 cms diamter not 7.8 so my maths were correct although I may have typoed the diamter!

I wish you were right but I have to face the fact that Heinz Beans in the pull top tin are denser than Asda own brand mushy peas. That fact is inescapable. I wish from the depths of my soul this was not the case but it is.

I think that a spanner would drop many, many times faster than any tin of beans of any make and I suspect that Neale was too upset by the sight of his lunch dissaperaing and so thought it actually sank faster than it did. Do not forget he thought he had lost his lunch for a whole 15 minutes and so was forced to continue the experiment under some considerable stress - thinking about it, this explains a lot. Certainly his observation was not in anyway scientific. In fact his only contribution to the scientific part of this debate has been the production of an image of a tin of Heinz Beans, hardly an MIT thesis is it?
