Use an aqua lung for that depth,
they supply air from the surface and you exhale
in water not in tube.
It is called Snuba with tubes that allow up to twenty foot depth.
Scuba is with tank on your back to depths of 100 feet.
Otherwise snorkle with just a 2 foot tube that allows
you to clear and breath different air always. You can still
dive down and hole breath and come back up to breath
out of snorkle.

Depending on the internal diameter of the tube and the material it is made out of, this will be nearly impossible. The deeper you go underwater, the more pressure is created from atmosperic pressure. It will basically crush the tube you are trying to breathe out of.

it's not about pressure. SCUBA gear is not 'assisted' breathing, it's just 'Self Contained Underwater Breathing Apparatus'. You still have to breathe on your own, and you can.
It's about the fact that you would never get enough oxygen.
Your lung capacity is not great enough to blow your exhale all the way out of the tube so fresh air could get in.

Don't quote me. but a twenty foot syphon tube would be a ***** to get stared as it were, and then you are 20 foot underwater think pressure on your body. I am sure some of our more mathematically gifted friends can startle you about the amount of pressure on you chest at that small depth.

you dont have enough lung pressure to clear the tube--- you cant do it above water either at 10 feet or even 5 feet. we are talking inches man of enough lung pressure to totally remove the air and refill it with fresh air. You will be breathing your own exhaled air in the first foot of tube. over and over...

You woundnt be able to expand your lungs enough to suck in ( create pressure difference ) between the air up there and the pressure where you are..
You might be able to do it 20feet underwater.. I dont know what the human limits are.. but try doing it 10 feet first and see how it works..

At 20 feet there will be a weight equal to a 20 foot column of water pressing against your lungs, making it imposible for you to breath un-aided. Divers use compressed air / oxegen to overcome this problem.

Because the pressure of the water will not allow your lungs to fill. The air must be at the same psi as the water pressure.

you have a tube that reaches down 20 feet?

You have to be able to clear the volume of air in the tube, or you'll asphyxiate.
