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

GENETIC ENGINEERING - EXAMPLE 27.2 : (a) Three genes, I, J and K are available. All these genes are linked with respect to one another. If the percent recombination between I and J is 8 %, that between J and K is 10 %, and that between K and I is 18 %, what is the order of the gene? (b) Twenty six genes, a, b, c, d, e, f, ... x, y and z are available. All these genes are linked with respect to one another. If the percent recombination between a and b is 3 %, between b and c is 3 %, between c and d is 3 %, ... between w and x is 3 %, between x and y is 3 %, between y and z is 3 %, then what is the percentage recombination between b and y?

Question 50 - An aqueous solution with 2.5 g of a protein dissolved in 600 cubic centimeters of a solution at 20 degree Celsius was placed in a container that has a water-permeable membrane. Water permeated through the membrane until the h - level of the solution was 0.9 cm above the pure water. (a) Calculate the absolute temperature of the solution, T in Kelvin, where T (Kelvin) = T (degree Celsius) + 273.15. (b) Calculate the osmotic pressure, P of the solution by using the formula P = hrg where h is level of the solution, r is density of water with 1000 kg per cubic meter, g = 9.81 N / kg as gravitational acceleration. (c) Calculate the concentration of the protein solution, C in kg / cubic meter. (d) Calculate the molecular weight of the protein, (MW) = CRT / P where R = 8.314 Pa cubic meter / (mol K) as ideal gas constant.

ENVIRONMENTAL ENGINEERING - QUESTION 22.3 : A well delivers 225 US-gallons per minute of water to a chemical plant during normal system operation. (a) Calculate its flowrate in the unit of mega US-gallon per day or MGD. (b) The following formula is written next to the chlorine feed point : (chlorine feed rate, lb / day) = (flowrate, MGD) X (dose, mg / L) x (8.34). If this formula is correct, then what should the chlorine feed rate to be in pounds per day (lb / day) if the desired dose is 2 mg / L. (c) Prove by calculations that the constant 8.34 in the formula next to the chlorine feed point is correct. Let 1 US-gallon = 3.78541 L and 1 mg = 0.0000022046 pound.
