Question

Prandtl number in heat transfer analogues to which dimension less number in mass transfer. a) Schmidt number b) Sherwood number c) Peclet number d) Stanton

Answer 1

a) Schmidt number

Step-by-step explanation:

Prandtl number in heat transfer is analogues to Schmidt number in mass transfer.

Prandtl number in heat transfer is the ration of momentum diffusivity to the heat diffusivity.

`P_r = (\\u)/(\alpha)`

Whereas, Schmidt number in mass transfer is the ratio of momentum diffusivity to the mass diffusivity.

`S_c= (\\u)/(\\u_(AB))`
