The essence of the problem
If we return to the laws of physics, it is worth recalling that the freezing water expands in volume by 8%. For example, if you have a 200 liter drum of iron, filled with water, after freezing it will be 216 liters of ice. To the container is not cracked, it is necessary to compensate for these 16 liters. Drain them in a barrel is not enough, because the amount taken into account in all directions. Use a method which involves the use of cans or plastic bottles (capacity 6 l).
The method
The principle of this method consists in that during the increase in volume, the ice will not crush the container wall and compress the canister which is in the water. In other words, after freezing you will have crumpled bottle, but the barrel is not signs of damage.
To build such a device may be as follows:
- Take a large bottle. The softer the capacity, the better.
- Close the container so that during pressing air out through the gap between the lid and the neck. Do not leave the can open, because it will be filled with rain water and sink to the bottom of the barrel.
- By the bottom of the canister tie the rope. If possible, tie the can down the chute.
- At the other end of the rope tie a brick. Tie on all 4 sides, otherwise the rope slide, load settle to the bottom.
- Lower the cargo into the water, holding the rope.
- The canister should be a float which is omitted in 3/4 water. Above the water should remain only loosely closed with a neck cap.
We have already mentioned that you need to compensate for the 16 liters of volume. Part will go up in a natural way, and the other you will have to compensate for their own. One canister compensate about 5 liters, so if possible, make the float 2.
To the bottom was not deformed, dip into the barrel 2 bottles (volume 2 liters). Do not forget to fill them with sand or fine gravel. The more air left in them - the better. Ice can not afford completely crush the container, but part of the volume will be able to compensate. Tie a rope to the bottle, otherwise they will lie on the bottom.
If you use this simple way, you can keep your barrel unharmed.
