Biology. 3. Quantitative – diffusion rate: Humans rely on their lungs to supply oxygen to their bodies. Each lung is made up of over 300 million alveoli or air sacs that provide a total surface area of 75 m2 over which oxygen can diffuse. However, the recent COVID pandemic has caused problems both during and after infection for oxygen delivery.

Oxygen is diffusing through a stagnant layer of methane 10 mm thick. The temperature is 20°C and the pressure 100 kN/m2. The concentrations of oxygen on the two sides of the film are 15% and 5% by volume. The diffusivity of oxygen in methane at 20°C and 100 kN/m2 is 2.046 x 10-5 m2/s. (i) Calculate the rate of diffusion of oxygen in kmol/m2s.

The partial pressure of oxygen in the lungs is about 150 mm of Hg. (The partial pressure is the pressure of the oxygen alone, if all other gases were removed.) This corresponds to a concentration of 5.3 × 10 24 molecules per m3. In the oxygen-depleted blood entering the pulmonary capillaries, the concentration is 1.4 × 10 24 molecules per m 3.
