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.

shape factor 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.

Third, Figure 14 shows a nonlinear reduction of fictitious number of cycles to failure with increasing

shape factor. This is reasonable.

(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.

Shape factor ([lambda]):

Shape factor based on volume & surface area of tomatoes was determined (McCabe and Smith, 1984) as;

Table 1--generally considered parameters Screw speed Barrel temperature settings Material feed rate Melt thermal homogeneity Viscosity Barrel diameter Core diameter Lead length Meter channel depth Channel width at the barrel Channel width at the screw core Average channel width Channel aspect ratio Total helical length of the metering section Flight width Flight start Helix angle at the barrel Helix angle at the screw core
