calculate the KLa value for the agitator

with the following values

OTR= 1 h^-1 L^-1

Fg = 0.018 m^3/s^-1

Cogi = 80 g/m^3

VL = 2.22m^3

CoL = 3 g/m^3

the equilibrium relationhship between the concentration of oxygen in the air (Cog) and the concentration of oxygen in the fermentation liquid (CoL) is given by

Cog= 35 CoL

use both equations

equation 1: OTR = KLa (Co*L - CoL)

equation 2: OTR = Fg (Cogi - Cogo)/VL
