Abstract
This paper presents a way to solve the transfer rate equation of oxygen in water. After running a calculation program, the graph of the function that indicates the increase of the dissolved oxygen concentration in the water as a function of time is plotted. Constructed in an original manner, the experimental installation allows the measurement of the increase of the dissolved oxygen concentration in water. The experimental obtained results are compared with the theoretically obtained data.

Summary
The temperature influences both the oxygen conditions, the dissolved O2saturation concentration and the mass transfer coefficient. The saturation concentration values are directly influenced by the water temperature [6]. The dissolved O2transfer rate in waterdepending on the temperature is given by the relation [7]: dC d a kL 200. Where: - akL–the transfer coefficient of the oxygen [s-1]; - Cs –the mass oxygen concentration at saturation[kg / m3]; - C –the current mass concentrationof the O2[kg / m3]. After integrating relation 1 applying the limit condition C = C0 for τ = 0, it results [6], [7]: dC Cs C a kL dτ (2).
