A tube that is 1 mm in diameter and 200 cm in length has a solution flowing within it. The viscosity of this solution is 0.01 g cm⁻¹
s⁻¹
and has a density of 1 g cm⁻³. The tube wall is porous to the transport of oxygen, and the oxygen concentration at the surface of the wall in contact with the solution is 175 μM. The diffusivity of oxygen in the solution flowing through the tube is equal to 2.3 × 10⁻⁵
cm²
s⁻¹. The pressure drop per unit length of the tube is 0.1 mmHg cm⁻¹. The solution entering the tube is free of oxygen. What is the concentration of oxygen (μM) in the solution as it exits the tube?
