    such as metals and mineral building material by surrounding media‚ which are usually liquid (i.e. corrosive agents)." Most metals corrode. During corrosion‚ they change into metallic ions. In some cases‚ the product of corrosion itself forms a protective coating. "For example‚ aluminium forms a thin protective oxide layer which is impervious to air and water. In other cases (e.g. iron)‚ however‚ the coating either flakes off or is pervious to both air and water. So the whole piece of metal can corrode

    ELECTROPLATING Electroplating is the application of electrolytic cells in which a thin layer of metal is deposited onto an electrically conductive surface. Electroplating is a plating process that uses electrical current to reduce cat ions of a desired material from a solution and coat a conductive object with a thin layer of the material‚ such as a metal. Electroplating is primarily used for depositing a layer of material to bestow a desired property (e.g.‚ abrasion and wear resistance‚ corrosion

    Lab design –Voltaic Cells Aim Of Experiment In this experiment‚ we are going to make a battery by making an electron current between the metals Zinc and Copper. We aim two study the voltaic cells and the transfer of electrons from the metal to the ion. The tendency for the electrons to flow from one chemical to another‚ such as from the zinc metal to the copper ion as shown here‚ is something that can be channeled and controlled. Channeling the flow of electrons is what we will take up in this

    Relationship between a model and Similitude For a model‚ similitude is achieved when testing conditions are created such that the test results are applicable to the real design. There are some criteria that are required to achieve similitude; 1. Geometric similarity – The model is the same shape as the application (they are usually scaled). 2. Kinematic similarity – Fluid flow of both the model and real application must undergo similar time rates of change motions. (Fluid streamlines are similar)

    applicable to fluids makes even the simplest tests to be a time consuming exercise. However‚ despite all these obstacles‚ over the years‚ people have managed to properly quantify the flow of a fluid. By establishing a dimensionless number called the Reynolds’ number‚ it is possible to divide various flows into three separate regions wherein each region with its governing equations. Introduced by the famous mathematician Stokes and
