    Study Notes

    Lubrication

    • A lubricant is a substance capable of reducing friction between two surfaces moving/sliding over each other.
    • Graphite is the most usual solid lubricant employed.

    Function of Lubricants

    • A lubricant reduces energy loss by minimizing friction between moving parts.
    • Lubricants act as anti-corrosive agents, protecting surfaces from corrosion.
    • Lubricants reduce the expansion of metal by minimizing heat generation due to friction.

    Chemical Engineering

    • Chemical engineering focuses primarily on the efficient use, production, design, transport, and transformation of energy and materials.
    • Chemical engineering is directly linked with mechanical engineering.
    • Chemical engineers are involved in the design and operation of plants.
    • Practicing chemical engineers may be accredited members of professional bodies such as the Institution of Chemical Engineers (IChemE) or the American Institute of Chemical Engineers (AIChE).
    • Chemical engineering uses principles of physics, mathematics, and chemistry to solve problems.
