If the Sink-and-float method is used to separate the same mixture of particles using a Pseudo liquid as medium made of suspension of fine ferrosilicon particles (ρPA = 6700 kg/m3) in water, at what content range (in vol %) of ferrosilicon solids in water should the medium be maintained for the separation? Hydraulic classification under free settling conditions in water at 20oC is used to separate a mixture of spheric particles having a size range of 5µm to 25µm. The densities of particles A and B are ρPA = 7500 kg/m3, ρPB = 2500 kg/m3 , respectively. For water at 20oC, density ρ = 1000 kg/m3 , viscosity µ = 1.005 x 10 -3 kg/m• s.
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
