Question

The Schmidt number which is defined as, &mu;/&rho; 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.-A-momentum diffusivity to the mass dif fusivity.

APTITUDE CRACK · Accepted Answer

The correct option is  A momentum diffusivity to the mass dif fusivity. The Schmidt number (&#119878;&#119888;Sc) is a dimensionless quantity used in fluid mechanics and heat transfer to characterize the relative importance of momentum diffusivity (kinematic viscosity), thermal diffusivity, and mass diffusivity in a fluid. The Schmidt number is defined as: &#119878;&#119888;=&#120583;&#120588;&#119863;Sc=&rho;D&mu;​ Where: &#120583;&mu; is the dynamic viscosity (momentum diffusivity) of the fluid, &#120588;&rho; is the density of the fluid, and &#119863;D is the mass diffusivity of the fluid. Therefore, the Schmidt number is the ratio of momentum diffusivity to mass diffusivity. So, the correct answer is: momentum diffusivity to the mass diffusivity.
