The volume of an airship is 150 × 104m3, the carrying capacity is 9 × 106n, and the air density is 1.29kg/m3. How much buoyancy does it bear in the air? How much weight does it weigh (g = 10N / kg)?

The volume of an airship is 150 × 104m3, the carrying capacity is 9 × 106n, and the air density is 1.29kg/m3. How much buoyancy does it bear in the air? How much weight does it weigh (g = 10N / kg)?

F=ρgv=1.29*10*150*10^4=19.35*10^6 N
The buoyancy of airship in the air is 19.35 * 10 ^ 6 n
The buoyancy of airship in the air is equal to the sum of airship weight and airship gravity
That is 9 * 10 ^ 6 + G = 19.35 * 10 ^ 6
So g = 10.35 * 10 ^ 6 n
Airship deadweight 10.35 * 10 ^ 6 n
