Consider an indoor environment inside which cigarette smoke containing harmful particulate matter is being produced and emitted. Assume that the cigarette starts generating smoke at t=0 minutes and is extinguished at t=10 minutes. Further assume the following: Volume of the indoor environment: 100 m3 Air exchange rate (λv): 1 h-1 Particle loss rate through capture using an indoor air purifier (kr): 0.2 h-1 Question: Derive the governing equation that describes the time-series profile of particulate matter as a function of time. It is sufficient to express the overall equation in terms of the variables above. Consider the time during and after the cigarette smoke is being generated

Question

Consider an indoor environment inside which cigarette smoke containing harmful
particulate matter is being produced and emitted. Assume that the cigarette starts
generating smoke at t=0 minutes and is extinguished at t=10 minutes. Further assume the
following:
Volume of the indoor environment: 100 m3
Air exchange rate (λv): 1 h-1
Particle loss rate through capture using an indoor air purifier (kr): 0.2 h-1


Question: Derive the governing equation that describes the time-series profile of particulate
matter as a function of time.

It is sufficient to express the overall equation in terms of the
variables above. Consider the time during and after the cigarette smoke is being
generated
