-
Calculation of mass transfer co-efficient is mostly/normally done using __________ theory.
-
The velocity, concentration and temperature boundary, for the boundary layer development on a flat plate during connective mass transfer will be same, if
-
For the gas absorption, the height of a transfer unit, based on the gas phase is given by (G: superficial molar gas velocity, L: superficial molar liquid velocity, FG:mass transfer co-efficient, mols/m2 , a: in-terfacial area per unit volume of tower)
-
Which of the following is used for the concentration of rubber latex ?
-
As the reflux ratio, in a continuous counter-current extraction is increased, the number of stages
-
In triangular co-ordinates, the ternery composition point falls __________ of the triangle.
-
In a single stage extraction process, 10 kg of pure solvent S (containing no solute A) is mixed with 30 kg of feed F containing A at a mass fraction xf = 0.2. The mixture splits into an extract phase E and a raf-finate phase R containing A at xB = 0.5 and xR = 0.05 respectively. The total mass of the extract phase is (in Kg)
-
Penetration theory states that the mass transfer co-coefficient is equal to (where, De is diffusivity and 't' is time)
-
Reboiler is considered as one theoretical plate, because
