Unformatted text preview: Henry’s Law Practical Problems- Oxygen C s = αPO2 = αPT f O2 Where: C s =Oxygen Saturation Level α = Henry’s constant (43.5 mg/l-atm @20oC & O ppt salinity) PO2 =Partial partial pressure of oxygen (.21 atm @sea level) at the controlling air/ water interface PT = Total atmospheric pressure (1 atm at sea level =33 ft of water=14.1 psi) f O2 = Fraction of oxygen in gas (0.21 for normal air) __________________________ 1) The saturation level of oxygen in a swimming pool in New Orleans? 2) The saturation level of oxygen in a swimming pool in Denver? Hint: total atmospheric pressure in Denver is 0.85 atm. 3) The Cs in the water of an open diving bell with an open bottom held with its internal water level at 33 ft in a fresh water lake. 4) The Cs in the water contained in a half filled balloon at a depth of 66 feet. 5) The Cs on a glass of water held on a shelf in air portion of the diving bell described in problem 3. 6) The Cs in tank half filled with water with a gauge pressure of 27 psi in New Orleans. 7) The Cs in a glass sitting on a table in a heavy metal submarine tank half filled with water in a freshwater lake at depth of 66 ft. The tank shows a gauge pressure of 1 atm. ...
