The volume of buoyancy airship is 2000m cubic meters, the weight is 4900n, and the air density is 1.2 Grade 8 Volume 1 Science Chapter 1 buoyancy help The volume of the airship is 2000m cubic meters, the dead weight is 4900n, and the air density is 1.29kg/cubic meter. How much buoyancy does the airship suffer in the air?
F floating = V row x P row x g (V is volume, P is density, g = 10 N / kg), airship is in the air, so V row = V boat, so f floating = 2000m ^ 3x1.29kg/m ^ 3x10 n / kg = 25800n,
[airship deadweight 4900n, then its maximum deadweight is (25800-4900) / 10 = 2090kg;] (expansion)
