ABSTRACT
The construction of the five (5) litre Electric Kettle was carried out in mechanical workshop of the Institute of Management and Technology Enugu. (I.M.T).
The fabrication process, included measuring and marking out operations of which the following dimensions was taken; the cylindrical body was taken as 170mm by 700mm in height and length respectively, the base diameter was 223mm, the lid diameter 140mm, length of nozzle 75min, water outlet and inlet were 20mm and 35mm, respectively and the drill position of the nozzle and heating element were 40mm and 25mm respectively.
The marked parts were cut out, filed for smooth edges, welded to form a drum like shape, insulating handle, cover and heating element were installed. At the end of the exercises, the electric kettle was fabricated.
The parent material used for the construction is the stainless steel, which was preferable for its easy workability, corrosion resistance and heat conductivity that is high. The stainless steel cannot contaminate food and drink.
The construction of electric kettle is recommended serve as heating equipment in our laboratory home, hospital etc. it also serves as a device which requires electricity conduction to generate heat to perfect its function. As well as in laboratories, industries foe heating and boiling of fluids. The mechanism of heat transfer in the electric kettle equipment is transferred into the liquid by firstly the metal conducting heat probably from electric source in contact by conduction and transfer the heat in the liquid causing the molecules of the liquid to expand colliding with one another exerting pressure and at equal prevailing atmospheric pressure which the under boils.
