This study is concerned about the gas exchange between air and water in plunging jet. Gas transfer by a plunging jet into a receiving pool of the same liquid is of particular interest to the engineers due to its importance in aeration and reduction of the carbon dioxide. A simple model is presented here which enables to estimate the gas transfer and discussed about gas transfer efficiency. Finally we have observed that the values of the gas transfer co-efficient and the gas transfer efficiency of plunging water jets are varied with jet velocity, jet thickness and jet power respectively.
