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

A 1.5 weight % aqueous salt solution is concentrated to 4 weight % in a single-effect evaporator. The feed rate to the evaporator is F = 7500 kg / h and the feed is at 85 degree Celsius. The evaporator operates at 1 bar. By assuming that only pure solvent of water exists in the form of vapor from the feed, calculate the flow rate of such vapor V.

Question 107 - In N + 1 Rule in Quantum Chemistry, whenever a spin 1 / 2 nucleus is adjacent to N other nuclei, it is split into N + 1 distinct peaks. In 1 peak or singlet, there is only 1 magnitude. In 2 peaks or doublet, the ratio of magnitude of each peak is 1 : 1. In 3 peaks or triplet, the ratio of magnitude of each peak is 1 : 2 : 1. In 4 peaks or quartet, the ratio of magnitude of each peak is 1 : 3 : 3 : 1. In 5 peaks or quintet, the ratio of magnitude of each peak is 1 : 4 : 6 : 4 : 1. (a) By using binomial coefficients or Triangle of Pascal find the ratio of magnitude of each peak if 6 peaks exists. (b) How many adjacent nuclei are available in a spin 1 / 2 nucleus in such situation of 6 peaks?

QUANTUM CHEMISTRY AND CHEMICAL ENGINEERING - EXAMPLE 31.1 : As an approximation, let v = Zc / 137 where v is the radial velocity for 1 s electron of an element, c is the speed of light, Z is the atomic number. For gold with Z = 79, find the radial velocity of its 1 s electron, in term of c and percentage of the speed of light. (b) As an approximation, let A x A = 1 - Z x Z / 18769 where A is the ratio of the relativistic and non-relativistic Bohr radius. Find the value of A.

Question 104 - In photoelectrical effect analysis of quantum chemistry, let E = kinetic energy of electron, p = intensity of UV light, f = frequency of UV light. According to Classical Theory, E = c for all values of f, E = mp. According to Quantum Theory, E = c for all values of p, E = mf + c. In a graph, m and c are constants where m is slope and c is y intercept. If m = 2 and c = 3 with similar value of E : (a) find the value of p according to Classical Theory; (b) find the value of f according to Quantum Theory.
