The volumetric mass transfer coefficient (kLa) is a parameter that determines the rate at which a gaseous compound (e.g. O2 or CO2) can transfer between the gas phase and the liquid phase. The ‘kL’ represents the rate of molecular diffusion through the gas-liquid interface and the ‘a’ represents the area of this interface per liquid ...
local energy dissipation rate. A correct representation of all four individual mechanisms, along with a correct prediction of the oxygen transfer rate, indicate a mechanistically robust bioreactor model.
15 mar 2020 · The liquid hold-up is constant and combining Eqs. (1) and (2) the following equation is obtained: (3) d C O 2 d t = k L a (C O2,s − C O2) where a= Ai / VL is the interfacial area for mass transfer per unit volume of the liquid into the vessel.
24 paź 2021 · The k L a (Volumetric Mass Transfer Coefficient) and the OTR (Oxygen Transfer Rate) detail how efficient oxygen is transferred from the gas bubbles into the bioreactor medium, i.e. how much oxygen is available for the cultivated biomass. The rate at which the biomass absorbs the available oxygen is described using the so-called OUR (Oxygen ...
Kiloliters to quarts (US liquid) conversion formula. Volume(qt) = Volume (kL) × 1056.6882094326
To convert Kiloliters to Quarts, multiply the Volume by the conversion ratio. One Kiloliters is equal to 1056.68815 Quarts, so use this simple formula to convert: Kiloliters = Quarts × 1056.68815. For example, here's how to convert 5 Kiloliters to Quarts using the formula above. 5 kL = (5 × 1056.68815) = 5283.44075 qt.
