Question

Penetration theory assumes that turbulent eddies travel from the bulk of the phase to the interface where they remain constant for a constant exposure time (te). The model correlating KL, mass transfer coefficient and DAB, diffusivity can be expressed as
A.KL = 2(DAB/πte)0.25
B. KL = 2(DAB/πte)0.5
C. KL = 2(DAB/πte)0.75
D. KL = 2(DAB/πte)

Answer 1

Penetration theory assumes that turbulent eddies travel from the bulk of the phase to the interface where they remain constant for a constant exposure time (te). The model correlating KL, mass transfer coefficient and DAB, diffusivity can be expressed as
A.KL = 2(DAB/πte)0.25
B. KL = 2(DAB/πte)0.5
C. KL = 2(DAB/πte)0.75
D. KL = 2(DAB/πte)


C. KL = 2(DAB/πte)0.75

↪Klotho is an enzyme that in humans is encoded by the KL gene. This gene encodes a type-I membrane protein .

☆☞ Here is ur answer ☜☆

✔✔ Penetration theory assumes that turbulent eddies travel from the bulk of the phase to the interface where they remain constant for a constant exposure time (te). The model correlating KL, mass transfer coefficient and DAB, diffusivity can be expressed as
A.KL = 2(DAB/πte)0.25
B. KL = 2(DAB/πte)0.5
C. KL = 2(DAB/πte)0.75
D. KL = 2(DAB/πte)


✔✔ANSWER ✔✔

✔✔ C. KL = 2(DAB/πte)0.75


✔✔ A gas and a liquid will come to some equilibrium relationship. It is valid for dilute solutions and non-reacting gases at near ambient. kL = liquid film mass transfer coefficient = DO2L.
