Problem- What is the concentration of TCE that moves though air only by diffusion at a distance of 10 m if the initial particle concentration at the point of generation are 100 µg/m3? Consider no other transport mechanism, but diffusion with flux of 1.1 x 10-5 µg/m2.s. The diffusivity coefficient of TCE at 1 atm and 200C is 0.082 cm2/s.
