different permeability. Variable porosity \(\varepsilon\) = 0.5,1.
Variable Re (0.1, 1, 5).
The variation of flow rate for different values of the permeability
factor in the cases of constant porosity (\(\varepsilon\) =0.5, 1) is
shown in Figure 4. In both the cases of porosity, the flow rate
increases rapidly as diameter increases from100 to500 µm. It is also
observed that the variation of pressure gradually increases as the
diameter of the vessel increases in the cases of constant porosity
(\(\varepsilon\) =0.5, 1). Furthermore, the pressure is increased when
the porosity factor increases at constant diameter as is shown in
Figures 5(a, b).
