The diffusional distance between the water and a capillary in the skin of a salamander is 1 μm. The Krogh’s diffusion coefficient is 25·10-6 nmol O2/sec·cm·mm Hg. Assume that the PO2 in salamander blood is 75 mm Hg, total atmospheric pressure is 760 mm Hg, water vapor pressure is 13 mm Hg, and α = 1.93 μmol O2/ml water·mm Hg. What is the rate of oxygen diffusion across a 1 cm2 patch of salamander skin?

The equation describing the linear relationship between hemoglobin concentration and absorbance at 520 nm is y=0.0523x+0.011. If the absorbance value is 0.6, calculate the % hemoglobin in whole blood.
The solubility of CO2 in blood is about 0.062 mL dL-1 mmHg-1. Arterial blood has a Pa_CO2 = 40 mm Hg and venous blood has PV_CO2 = 46 mm Hg, and cardiac output is 5 L min-1. A. Calculate the content of dissolved CO2 (in mL dL-1) in arterial and venous blood and how much CO2 is removed from the tissues and delivered to the lungs per minute. (Hint: CO2 content = solubility of CO2 * PCO2) (Hint: Rate of CO2 transport = cardiac output * (arterial CO2 content – venous CO2 content) B. If the volume diffusion rate of CO2 = 200 mL min-1 in the lung, what fraction of the total CO2 removal is accomplished through carrying dissolved CO2? C.

A membrane can separate gas mixture because different gases have different permeability through the membrane. The permeate flux across unit membrane area under unit pressure gradient is called permeability and the ratio between the permeability of gas A and that of gas B is defined as selectivity of A to B. Membrane separation process depends upon five separation mechanisms including molecular sieving, Knudsendiffٴusion, solution diffٴusion, surface diffusion, and capillary condensation. Using a schematic diagram, elaborate on the mechanism of surface diffusion and solution diffusion in membrane separation.
