12.4.2 Applied Voltage
Figure 9(a), (d), and (e) show the effect of applied voltage on AFD. In this work, the
AFD suffer an increase followed by a decrease with increasing the applied voltage.
The surface plot in Figure 9(a) indicated that there was a considerable interaction
between applied voltage and solution concentration and this is in agreement with the
presence of the term

in the model of AFD. In the present study, applied voltage
influenced AFD regardless of spinning distance and volume flow rate as shown in
Figures 9(d) and (e). The absence of
