ABSTRACT
The project title “fabrication of flow nozzle†was done by a selected group of Engineering Students and the practiced objective (aim) of the project was centered on constructing a nozzle that is capable of transporting fluid from one to the other, to determine the charge in velocity of the moving fluid across two given areas of the nozzle and to be able to measure the quantity of fluid that will flow through the nozzle for a given period of time.
However, the construction of the nozzle was done with materials obtainable locally and the science of operation carried out in constructing the nozzle was; cleaning, marking out, cutting off, drilling, folding, centre punching, assembling, welding, filling, testing and painting.
The flow nozzle was constructed based on the following specifications and dimensions;
Throat Diameter60mm
The diameter of the duct pipe 140mm
The length of the up stream pipe 200mm
The thickness of the nozzle3.8mm
The length of the down stream pipe 200mm
The height of the nozzle820mm
The length of the nozzle690mm
The size of the pressure valves½ inch
Furthermore, the selection of materials for the construction of this flow nozzle was based on the factors which includes; ductility, malleability, fabricability, mechanical strength and stability, availability, corrosion resistance and lastly cost factor.
Finally, the constructed flow nozzle and all other expenses cost N8,000.
