The Schmidt number which is defined as, μ/ρ D, is the ratio of the
A. Momentum diffusivity to the mass dif-fusivity
B. Thermal diffusivity to the mass diffusivity
C. Momentum diffusivity to the thermal diffusivity
D. None of these
Answer: Option A
Solution (By Examveda Team)
The Schmidt number (Sc) is a dimensionless number in mass transfer operations.It is defined as the ratio of momentum diffusivity (kinematic viscosity, μ/ρ) to the mass diffusivity (D).
In mathematical terms, Sc = μ / (ρ D).
This number helps compare the relative effects of momentum and mass transport within a fluid.
