The dimensionless number in heat transfer corresponding to Sherwood Number in mass transfer is
Options:
(A) Biot Number
(B) Schmidt Number
(C) Nusselt Number
(D) Graetz Number
Official Answer Key:
C
Step-by-Step Solution & Explanation
Sherwood number Sh = k_c·L/D_AB (dimensionless convective mass-transfer coefficient) is the direct mass-transfer analogue of the Nusselt number Nu = h·L/k (dimensionless convective heat-transfer coefficient). Schmidt number is the mass-transfer analogue of Prandtl number, not Nusselt — a common distractor pairing.
