So here is my theory. If you did all the math, (which I did),  and made a syrup of the exact viscosity. Would that syrup flow like water underwater just like water flows in air.

Here is a diagram with all the math there for you.

I created a simple ratio... the number at the bottom right is my perfect syrup viscosity.

Water can flow in water...

In places under the sea underwater rivers have been found, from what I remember it had to do with the salinity and temperature of the water...

Yes, I know. I've seen that on tv. I just want the perfect ratio so it would move in the same manner underwater.Not as fast, but nontheless it would.

If you where to do more math, and filmed normal water in the the exact amount of frames per second it might look somewhat the same.

Get ya now, so you need a sort of viscous fluid, denser and non soluble with water...

Could maybe concoct something using oils and something oil soluble but not water soluble for density...

Goodhart (author)2012-05-19

Oils come in a variety of viscosities, especially motor and gear oils.

Goodhart (author)2012-05-19

not only that, but "streams" like the Gulf stream, are warmer then the surrounding ocean and flow up the coast and warm the east coast of the USA

Air flow is viewed by means of fluid dynamics.

vroom...vroom... (author)2012-05-17

What are you saying? I understand that.

Goodhart (author)2012-05-17

All I am saying is that anything to do with fluid dynamics can be applied here too. For instance: you can take two "flasks" , fill one with CO2, and the other with O2. Now, pour the CO2 into the one with O2 and it will "displace it" (flow to the bottom and push the Oxygen up and out of the flask) as it has a higher density (viscosity).

Now, as someone else mentioned, if the "syrup" you are using is water soluable, some of it will mix (at the line of demarcation) and it's action will be a bit different then if the syrup is nonsoluable.

My comment was meant only to say that since fluid dynamics apply in both cases, one can use the same methods of calculation in both cases.

So I thought. I still am not sure of how pressure effects this experiment.

Goodhart (author)2012-05-18

Well, the answer to:  Would that syrup flow like water underwater just like water flows in air
then, is yes, if they couldn't "mix" and the ratios were comparable. .

vroom...vroom... (author)2012-05-18

Cool! I still would like someone to try it.

Goodhart (author)2012-05-19

The "difficulty"" would be in getting the ratios of the densities the same. Water is to air as "what" is to water......and to add to what I posted above.....it would "flow the same way" but not at the same SPEED since water is denser then air, the "syrup" would be tremendously denser then the water......ergo a MUCH slower flow.

Hot wax, a flowing lava lamp?

Goodhart (author)2012-05-19

Yes, and if you notice, the "wax" flows like water, but much MUCH more slowly.

vroom...vroom... (author)2012-05-19

Yes, exacts are the only way to go.

Goodhart (author)2012-05-19

Well, in much the same way that super sizing something "to scale" will "slow it down" I am afraid that making it that viscous will ultimately have the same results.

"flow like water underwater just like water flows in air"

Flow where?

Sorry if I wasn't clear. I'm asking if the syrup would act like water in water like water acts in air. If that makes any sense at all.

lemonie (author)2012-05-16

vroom...vroom... (author)2012-05-16

Again, if I had it, I would.

lemonie (author)2012-05-17

If it's a water-based syrup, it's not going to behave in the right way.
Can you get some "white-spirit" or lighter-fluid?

vroom...vroom... (author)2012-05-17

I can try.

Don't know if your equation means anything. You are trying to compare how a liquid behaves in a gas to how a liquid behaves in a liquid. They may all act like fluids but more factors are involved like density, molecular forces where the two substances meet, velocity and pressure, etc.

vroom...vroom... (author)2012-05-15

I think this would just be a cool experiment though, someone should try it.
