Use a pressure inerting procedure with nitrogen to reduce the oxygen concentration to 1 ppm. The vessel has a volume of 3.78 m3 and is initially contains air, the nitrogen supply pressure is 4,136 mm Hg absolute, the temperature is 24°C, and the lowest pressure is 1 atm. Determine the number of purges and the total amount of nitrogen used (in kg). Repeat for a vessel with a volume of 37 m3 and a supply pressure of 3000 mm Hg.

Use Henry's law and the solubilities given below to calculate the total volume of nitrogen and oxygen gas that should bubble out of 1.6 L of water upon warming from 25 ∘C to 50 ∘C. Assume that the water is initially saturated with nitrogen and oxygen gas at 25 ∘C and a total pressure of 1.0 atm. Assume that the gas bubbles out at a temperature of 50 ∘C. The solubility of oxygen gas at 50 ∘C is 27.8 mg/L...

The partial pressure of oxygen in the lung alveoli is a bit lower than in ambient air, being about 100 mm of mercury, or 0.13 Atm (it is lower than the partial pressure in air mainly because oxygen is continually taken up by the alveolar capillaries and carbon dioxide is continually released into the alveoli). In cell-free blood plasma (or a saline solution formulated to match key characteristics of blood plasma), which lacks red blood cells and therefore lacks hemoglobin,...
