Description
In hydroculture it is important to figure out the most effective method to supply oxygen to the root.
This paper is designed to study the factors to increase the supply of DO(dissolved oxygen) by using severaltypes of nozzles. The nozzles have been developed after our study of some commercialized nozzles.
In the case of oriffice nozzle, we find that a maximum DO can be obtained through the adjustment of the oriffice in size and in number.
Under the oriffice, the use of two meshes with 1.5(mm) apart from each mesh cause higher DO.
In the case of venturi nozzle, it has also found that a combination of the reduced angle 90°and the extended angle 130°in venturi can generate a higher DO.
