region and other regions have uniform pressure which leads to smoother dispersion
of slurry without any interrupted flow (Fig. 5).
2.3 Case(ii): Effect of Varying the Viscosity
Through varying the viscosity from 150 to 225 Pa s, the inlet pressure is determined
by performing CFD analysis. The liner relationship holds between pressure and
viscosity as seen from Fig. 6. The pressure contour shown in Fig. 7 and 8 indicates
