how much weight will 10 -15 gallon barrels hold?
How much weight does it take to sink a 55 gallon barrel?
US gal = 3.785 L, total volume, is the 208 you calculated. That gives you a displacement of 200 Kg shall we say?, or the 441Lbs you calculated. That's it. L
. ~ 8.33 pounds/gallon minus the weight of the barrel
I got about 441lbs. for the 55 gallon drum
That's 250 litres. You can use Archimedes' principle which states "A body immersed in a fluid is buoyed up by a force equal to the weight of the displaced fluid". In other words, how much water will the barrel displace, how much will the displaced water weigh? That should allow you to work it out, I didn't just want to do it for you.
I get about 208 liters out of 55 gallons. Thanks for the info
