Gewicht von Gasen

Luft: 1,293 g/L | Stickstoff: 1,251 g/L

das entspricht bei 200Bar
- D12 = 6,2 kg
- D7 = 3,6 kg
- M15 = 3,9 kg
- S10 = 2,6 kg
- S7 = 1,8 kg

Sauerstoff: 1,429 g/L

das enspricht einem Gewicht (50er Nitrox)
- 10L Stage = 1,4kg + 1,3kg = 2,7kg
- 11,1L = 1,6kg + 1,4kg = 3 kg

bei einem 100% O2
- 7L Stage = 2 kg

32er Nitrox
- D12 = 2,2kg O2 + 4,2kg Air = 6,4 kg

36er Nitrox
- D12 = 2,5kg O2 + 4kg Air = 6,5 kg

Helium: 0,1786 g/L

21/35 Trimix
- D12 = 1,4kg O2 + 2,6kg N + 0,3kg He = 4,3 kg

Argon: 1,784 g/L

0,85L = 300g

Gewicht von Flaschen:

D12 = 2x 14,1kg
Auftrieb leer : -0,28 kg x 2 = -0,56 kg
Auftrieb voll : - 3,45kg x 2 = -6,90 kg

The cylinder is made of 14.1 kg of steel, (which has a density of 7.8 kg/litre).
The steel therefore has a volume of 14.1 / 7.8 = 1.81 litres, so the total volume is 12 + 1.81 = 13.81 litres.
The density of fresh water is 1 kg/litre, giving 13.81 x 1 = 13.81 kg

Air has a density of 0.0012 kg/litre.
The air in a full cylinder weighs 0.0012 x 220 bar x 12 litres = 3.17 kg.

The cylinder when empty has a buoyancy of 13.81 kg - 14.1 kg = -0.28 kg
The cylinder when full has a buoyancy of 13.81 kg - 14.1 kg - 3.17 kg = -3.45 kg

D7 = 2x 9,11 kg
Auftrieb leer: -0,93 x 2 = -1,86 kg
Auftrieb voll : -2,78 x2 = -5,56 kg

The cylinder is made of 9.11 kg of steel, (which has a density of 7.8 kg/litre).
The steel therefore has a volume of 9.11 / 7.8 = 1.17 litres, so the total volume is 7 + 1.17 = 8.17 litres.
The density of fresh water is 1 kg/litre, giving 8.17 x 1 = 8.17 kg

Air has a density of 0.0012 kg/litre.
The air in a full cylinder weighs 0.0012 x 220 bar x 7 litres = 1.85 kg.

The cylinder when empty has a buoyancy of 8.17 kg - 9.11 kg = -0.93 kg
The cylinder when full has a buoyancy of 8.17 kg - 9.11 kg - 1.85 kg = -2.78 kg

M15 = 17,8 kg
Auftrieb leer: -0.51 kg
Auftrieb voll : -4,47 kg

The cylinder is made of 17.8 kg of steel, (which has a density of 7.8 kg/litre).
The steel therefore has a volume of 17.8 / 7.8 = 2.28 litres, so the total volume is 15 + 2.28 = 17.28 litres.
The density of fresh water is 1 kg/litre, giving 17.28 x 1 = 17.28 kg

Air has a density of 0.0012 kg/litre.
The air in a full cylinder weighs 0.0012 x 220 bar x 15 litres = 3.96 kg.

The cylinder when empty has a buoyancy of 17.28 kg - 17.8 kg = -0.51 kg
The cylinder when full has a buoyancy of 17.28 kg - 17.8 kg - 3.96 kg = -4.47 kg

10L Alu =

7L Alu = 9 kg
Auftrieb leer: -0,84 kg
Auftrieb voll: - 2,69 kg
