Caption: FIG 2: The Impact of Shape Factor
on Drag Flow: When the ratio of the channel depth to width (h/W) of a screw channel increases, there is a reduction in its drag flow.
The effect of the nanoparticle shape factor
on the temperature profile of the nanofluid during the squeezing flow is shown in Figure 14.

of the solid grains and the liquid fraction as a function of the temperature.
where S and N are the shape factor
and stability parameter, respectively.
On the other hand, stitch density, loop shape factor
, and take-up rate of knitted fabrics depend on wpc and cpc in addition to loop length, as shown in the results of this research.
(ii) The obtained coefficients, peak and shape factors
, may be applied as potential benchmarks for the identification of electric arc purposes regardless of voltage value, and it may be crucial for diagnosis of electrical apparatus.
where [G.sub.c](s) = -(s[square root of -j]/4)([J.sub.1](s[square root of - j])/[J.sub.0](s[square root of -j]))/[l-(2 /s [square root of -J]) ([J.sub.1](s[square root of -j])/[J.sub.0](s[square root of -j]))] and s = c[(8[omega][[rho].sub.0][[alpha].sub.[infinity]]/[sigma][phi]).sup.1/2]; [[alpha].sub.[infinity]] is the tortuosity of the PFMM; [[rho].sub.0] is the static density of air; [sigma] is the static flow resistivity; [phi] is the porosity; [omega] is the angular frequency; and c is the shape factor
. In (1), the value of static flow resistivity is usually measured but the relationship between the static flow resistivity and geometrical parameters of the PFMM cannot be revealed.
In Figure 7 we show average shape factor
<[delta]> versus the number of segments out of channel s.
