Question
Transcribed Image Text:The pressure drop is to be 20 in Hg. If the filter cake contains 5X% moisture
(wet basis), calculate the filter area required to filter 10 gal/min of slurry when the filter
of CaCO3 containing 14,7 lb of solid per cubic foot of water (236
with 3X% submergence is to be used to filter a concentrated
cycle time is 5 minutes. Assume that the specific cake resistance is 2,9 x 1010 APO 26
and that the filter-medium resistance Rm is negligible. The temperature is 20°C
X is the last number in your NIM!
2. A bed of ion-exchange beads 8 ft deep is to be backwashed with water to remove dirt.
The particle have a density of 1,24 gr/cm³ and an average size of 1,1 mm. What is the
minimum fluidization velocity using water at 20°C, and what velocity is required to
expand the bed by 25%? The beads are assumed to be spherical and EM is taken as 0,4
3. A flat-blade turbin with six blades is installed centrally in a vertical tank. The tank is 6
ft in diameter; the turbine is 2 ft in diameter and is positioned 2 ft from the bottom of
the tank. The turbine blades are 5 inch wide. The tank is filled to a depth of 6 ft with a
solution of 50% caustic soda, at 150°F, which has a viscosity of 12 cP and a density of
93,5 lb/ft3. The turbine is operated at 90 r/min. the tank is baffled. What power will be
required to operate the mixer?
