The airflow via the channel in Figure 7 illustrates how air will penetrate the masks whenever the user breathes in. Air from the surrounding setting is compelled into the numerous tiny pores on the mask. From Equations and , it is clear that the bigger the distinction in the areas the air flows through or the smaller is the masks pore, the higher the stress drops or adverse differential strain. In different phrases, the harder it is for the wearer to breathe via the masks.
