Water
If you filled a British Beer Barrel with water, it would weigh 163kg, or 359lb. If you have a barrel that you want to know the volume of, then we need to know the height, the radius of the widest part, and the raduis of the top. For other barrel sizes, look at en.wikipedia.org/wiki/Barrel_(unit)
Dehydration you need to drink water
To sink a 15-gallon barrel, you would need to add enough weight to overcome its buoyancy. A 15-gallon barrel typically displaces about 15 gallons of water, which is approximately 125 pounds (since 1 gallon of water weighs about 8.34 pounds). Therefore, you would need to add at least 125 pounds of weight to sink the barrel, though additional weight may be required to account for any air trapped inside or to ensure it remains submerged.
You would need to know the length and height of the ramp.
If the water is likely to freeze, then I would definitely bring it indoors.
the barrel? or what? why would you need to turn something into a pen? unless you pen spin. then you need to buy the pen with the correct barrel and take it apart.

To make a barrel planter, you will need a large barrel, drill drainage holes in the bottom, fill it with soil, and plant your desired plants. Make sure to water and care for the plants regularly.
