Answer / heamnth

the minimum fludisation veocity is the velocity of the gas
or liquid at which the bed pressurecdrop in the bed equals
to the weight of the bed.

Answer / sujeetha

the superficial fluid velocity at which the upward drag
force exerted by the fluid is equal to the apparent weight
of the particles in the bed".

Answer / akhil

minimum fluidization velocity is the superficial velocity of
the fluid in a fluidized bed at which the drag force by the
upward moving fluid is equal to the weight of the solid
particles.

Answer / rajesh kumar bhagat

for minimum fludization velocity we increase the flow of fluid
in the bed to be fludized. then let the bed Seattle and re-
increase the flow rate of fluid, the minimum velocity at which
bed re-fludized is called minimum fludization velocity.
theoritically it can be determined by erguen equation or buke
pulmer equation.

Answer / deepak

Minimum fluidization velocity is that,the pressure drop across the bed must be equal to the effective weight per unit area of the particles at the point of incipient fluidization.

Answer / swaraj panda

superficial velocity at the point of fluidization is known as minimum fluidization velocity

Answer / pradeep

minimum fluidization velocity can be defined as the velocity
at which the pressure drop reaches to maximum,at that point
the velocity is called as minimum fluidization velocity

Answer / mustaqeem ali khan

when frictional forces counter the gravitational forces then it is called monimum fludization

Answer / giri

the velocity where true fluidisation will begins

BIOCHEMICAL ENGINEERING INSTRUMENTATION - EXAMPLE 29.5 : The following formula is used as a reference : (analyte signal) / (internal standard signal) = (f-factor) x (concentration of analyte) / (concentration of internal standard). A solution containing 3 mM of analyte and 4 mM of internal standard gave peak signals of 2 and 3 mamps respectively. Another similar solution containing 2 mM of analyte and 1 mM of internal standard gave peak signals of 1 and 4 mamps respectively. Find the average f-factor.

Question 64 – According to a heuristic of chemical engineering plant design, assume a pressure difference dP = 4 psi for each 10-ft rise in elevation. A pump is needed to pump liquid from a storage tank at a lower elevation to a heating tank at a higher elevation with the elevation difference of 60 ft. (a) Find the pressure loss due to such elevation. (b) If the required minimum inlet pressure to the heating tank is 9 psi, with 1 control valve is installed between pump and heating tank, what is the dP minimum required for the control valve and the entrance to the heating tank when the heuristic mentions that at least 10 psi is required for the control valve? (c) The pressure at the inlet of the pump is 8 psi and the flowrate of the liquid produces pressure head of 50 psi. What is the total pressure produced by the pump? (d) Assume a pipeline dP of 2 psi / 100 ft for liquid flow in a pipe according to heuristic, what is the approximate maximum length of the pipe in ft that can be installed between the pump and the heating tank?
