(a) Determine the size range for the various fractions obtained during settling.
Sub: Seperation Process
A mixture of solid particles, consisting of silica (B) and galena (A), with particle sizes ranging from 1.27 × 10^2 mm
to 5.08 × 10^2 mm, is intended to undergo hydraulic classification. This process involves free settling in the laminar
region within water at a temperature of 293.2K. The specific gravity of B is 2.65, while that of A is 7.5.
(a) Determine the size range for the various fractions obtained during settling.
(b) Calculate the terminal settling velocities vt(m/s) for particles A and B within the size range of 1.27x10^2 mm to 5.08x10^2 mm.
(c) Utilize Excel or other contemporary tools to plot a graph of vt(m/s) against particle diameter Dp (m) for the specified size range of particles A and B.
(d) Establish the similar values of vt(m/s) for both A and B from the plotted graph. Verify these values through calculation.
(e) Compute the value of the largest Reynolds number observed.
(f) Based on the information presented in (c) to (e), elucidate this hydraulic classification process.
(g) Drawing upon your understanding of separation processes, recommend and justify an alternative method
for sorting these two particles.
