Response to the following problem:
Compute the collection efficiency of a cigarette filter which is a fiber layer of thickness 1 cm and void fraction 0.5. Assume that the smoke particles are a monodisperse aerosol of diameter 0.2 itm and density 1 g cm-3 and that the fiber filaments have a diameter of 50 pm. Smoke is inhaled at a velocity of 3 cm s-1 and at 298 K and 1 atm.
