Reynolds (Rei) number for the impeller is given by (where Di, stirrer diameter; N, stirrer speed, ρ, density of fluid and μ, viscosity of fluid)

Question: What is the effect of the concentration of dissolved salts and sugars on the oxygen transfer rate?
[A].

The saturation concentration of oxygen in the medium decreases with the concentration of dissolved salts and sugars, leading to a lower oxygen transfer rate

[B].

The KLa of the medium decreases with the concentration of dissolved salts and sugars, leading to a lower oxygen transfer rate

[C].

The KLa of the medium increases with the concentration of dissolved salts and sugars, leading to a lower oxygen transfer rate

[D].

None of the above
