3. A storage tank with a surface area of 35 m² and a wall thickness of 100 mm contains 2000 kg of hydrogen gas at a concentration of 110 kg/m³. The atmosphere outside the tank has a hydrogen concentration of 0.2 kg/m³. If D = 8×10-11 m²/s, how long will it take (in years) for 4% of the hydrogen to diffuse out of the tank? Assume steady-state conditions.
