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.
