How many feet would a garden hose have to be under water to collapse.?

Answer 1

Hi

The design of specific garden hose you choose will have somewhat varying rigidity (stiffness). This physical strength would need to be overcome by the external pressure in order to collapse the hose.

If the hose is not pressurized internally, the issue depends on where the ends of the hose are located, and what is inside the hose.

If the hose were fiilled with WATER, the hose ends are open at both sides and are both under water the external pressure would equal the internal pressure regardless of the depth and the hose would not collapse.

If the hose were filled with AIR, the hose ends are open at both sides and are above the surface of the water the weight of the water above the hose would expell the air freely, so only the pressure needed to overcome the stiffness of the hose is needed

If the hose is pressurized, the issue is how much pressure is required on the outside the hose, due to the depth underwater (pressure created by the weight of the water) to overcome the pressure is on the inside of the hose (pressure from the hoses source) and the pressure required to overcome the stiffness of the hose.

So this would have to be calculated for the specific depth at which the hose is placed.

I hope by this point you can see there are many scenarios, each with a different answer.

If there is some specific problem you are trying to solve, post another question with HOSE in the text and I will try to get closer to what you need.

Answer 2

a garden hose dropped in the ocean.if both ends are open wont do anything but float to the bottom of 5 miles of water,a sealed at both ends hose with water put in at sea level will become wrinlked a bit when landing on sea floor,an air filled hose woll collapse and wrinkle a lot,,,,,air will be compressed greatly because of water pressure a 5 mi depth,,,,i just ate dessert,don't feel like lookin that up,,,,,,,

Answer 3

It would collapse only if the pressure on the outside was significantly higher than the pressure (air, water, or whatever) on the inside. To answer that for some particular hose, see if you can collapse it by standing on it, and calculate the pressure you are applying.

Answer 4

Since there are MANY varieties (re-enforced, thin, thick, etc) and manufacturers, this is a very broad question.

You MAY be able to find out how much weight you can place on the hose..........you would need a 1 inch by 1 inch pad as your pressure point since we are dealing with Pounds per sqare inch.

as force (weight) is applied to a 1 X 1 inch contact point...you will need to find the point at which the hose flattens out under this pressure and this will give a MOSTLY scientific answer to how many pounds per square inch (PSI) is required to flatten the hose.........THEN

Use this calculator to find the depth......

hope this helps

Answer 5

If the hose is underwater and open at both ends it wouldn't collapse.

If it was sealed and had air inside of it there are several variables that need to be taken into consideration:

What material is it made from?
If it is made from rubber, is it vulcanized?
How thick is the hose?
Is it hardened or reinforced in any way?
.

Answer 6

Assuming it was full of air, it would depend on the material makeup of the garden hose.

Answer 7

It would not collapse unless it was full of air.
