The typical diameter of an alveolus is 0.3 mm. The surface tension of water is about 70 dyne cm-1. The dyne is the unit of force in the cgs system: 1 g cm s-2. It is converted to N by multiplying by 10-3kg g-1x 10-2m cm-1 = 10-5 kg g-1 m cm -1. What is the pressure within this alveolus assuming no surfactant at mechanical equilibrium? Give the answer in Pascals (N m-2) and in mm Hg.
