Transcribed Image Text:Solid particles having a diameter of 120 μm and a density of 1000 kg/m³ are to be fluidized with air. The
cross section of the empty bed is 0.3 m². Assume the simplified equation of Wen and Yu for Remf between
0.001 and 4000
Remf
Where:
= -33.7+ 1136 + 0.0408
x³p.(Ps - p)g
μ²
2
x is the particle diameter
p is the density of the fluid
Ps is the density of the particles
Air is used as the fluidization material at 25°C at 2 atm absolute pressure.
a) Reynolds number at minimum fluidization
b) minimum fluidization velocity in mm/s
c) volumetric flow of the air in scfm (standard cubic feet per minute) if the bed were operated at 8
times that required for minimum fluidization (standard temp, in this case, is 20 °C).
