Lecture 31: Examples on pressure drop calculations
Examples on packed bed calculation
Shown below is the schematic of a 0.2 m ID U-glass tube to a depth of 1m with 10,000 spherical quartz particles (). What will be water (
) flow rate required through the bed if the water level is kept 2 m above the top of the packed bed? The particles are held between the two sieves.
(Fig. 31a)
Solution: Apply the ME balance between (1) and (2) incorporating frictional loss in the packed–bed:
particles (
). What will be water (
) flow rate required through the bed if the water level is kept 2 m above the top of the packed bed? The particles are held between the two sieves.
