A cylindrical tube connects two large gas tanks (Tank-1 and 2). Both tanks contain mixture of carbon dioxide (CO₂) and sulphur dioxide (SO₂). The partial pressure of carbon dioxide in Tank-1 is 80 kPa and in Tank-2 is 20kPa. Both tanks and connecting tube are at 100 kPa and 263 K. The tube is 100 mm long. The diffusion coefficient of carbon dioxide is 0.064 cm²/s at 100 kPa and 263 K, and molar mass of carbon dioxide is 44 kg/kmol. Calculate the steady-state flux of carbon dioxide through the tube, assuming ideal gas is applied. 11.755 x 10-3 mol/m².s 7.755 x 10-3 mol/m². 4.755 x 10-3 mol/m².s 1.755 x 10-3 mol/m².s
