Mass Transfer Lab By Innovative Research Equipments

The set-up consists of an open water tank with variable speed paddle mixer. Air is supplied to the water from the bottom and mixed in the water by operating stirrer. Speed of the stirrer can be controlled with the help of speed controlled provided in the Panel. Flow of air entering in the water tank is directly metered with the help of Rotameter and can be regulated by means of Valve provided in the set-up. Three air diffusers of different types are provided with the set-up and are interchangeable. Desired diffuser can be easily installed on the air inlet to the water tank. A Temperature Indicator is also provided which gives the direct reading of water temperature.The present set-up is complete in all respect to demonstrate the oxygen transfer characteristics of diffused air system. A battery powered Dissolved Oxygen Meter accompanies the apparatus which allows to conduct the experiment with ease
