A.
Pr = Sc; percentage change in heat and mass transfer flux will be the same for a given change in the degree of turbulence.
|
|
B.
Pr = Sc = 1; total mass, momentum and thermal diffusivity will be the same.

C.
both (a) and (b)

|
D.
Pr = Sc ; there won't be any change in heat and mass transfer flux with changes in degree of turbulence.
