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

Measuring Dissolved Oxygen Concentration in Aquaculture
(DO) is considered the most important water quality variable in fish culture. In the broadest sense, however, dissolved oxygen concentration is no more important than other environmental variables because any factor that is outside the range tolerated by fish can cause stress or death. What makes dissolved oxygen concentration so important in intensive fish culture is the speed with which it ca...
متن کاملApplication of Gene Expression Programming to water dissolved oxygen concentration prediction
This research based on record and collected data from four stations at Eymir Lake, Turkey, which are monitored daily in seven months. Water quality monitoring using former methods are time-needed and expensive, while the application of gene expression programming is more understandable, rapid, and reliable which is used in this article to provide a prediction for dissolved oxygen. The concentra...
متن کاملDissolved Oxygen Concentration Interlaboratory Comparison: What Can We Learn?
Dissolved oxygen concentration is a key parameter for characterizing natural and wastewaters and for assessing the global state of the environment in general. The decrease of dissolved oxygen levels in the world’s oceans, which is becoming increasingly obvious, is expected to have an impact on the whole ecosystem of the Earth, including the carbon cycle, the climate, etc. Dissolved oxygen measu...
متن کاملThe effect of dissolved oxygen concentration on the growth physiology of Saccharomyces cerevisiae whi2 mutants.
Isogenic whi2 and WHI2+ strains of Saccharomyces cerevisiae were grown in a 2-litre bioreactor as batch cultures on a medium containing yeast extract and peptone with either glucose or ethanol as carbon and energy source. The concentration of dissolved oxygen within the medium was varied over the range of 0 to 100% saturation. Expression of the whi2 phenotype only occurred above 40% oxygen satu...
متن کاملMeasurement of Dissolved Oxygen in Swamp Waters. Further Modification of the Winkler Method
INTRODUCTION There have been several modifications of the original Winkler method for the estimation of dissolved oxygen (Winkler, 1888) designed to overcome the sources of error due to the presence of oxidizing and reducing substances in natural waters and industrial wastes. In the course of work on tropical swamps we have been interested in the amount of oxygen in water which not only may con...
