Alternative Form of Total Flux Plot

Therefore, upward propagation velocity of this layer = - = — = 0.577 cm/s 

A suspension in water of uniformly sized sphere (diameter 150 pm, density 1140 kg/m has a solids concentration of 25% by volume. The suspension settles to a bed of solids concentration of 55% by volume. Calculate  

Equation (3.28) allows us to calculate the velocity of interfaces between suspensions of different concentrations. 

The velocity of the interface between initial suspension (B) and clear liquid (A) is therefore  

Assuming Stokes law applies, then n — 4.65 and the single particle terminal velocity is given by Equation (2.13) (see Chapter 2)
