Core Disciplines
Thermodynamics
Overview:
- Thermodynamics is the study of energy, heat, and work. It involves understanding how energy is transferred and transformed within physical systems.
Key Concepts:
- Laws of Thermodynamics: These laws describe how energy moves and changes form. For example, the first law states that energy cannot be created or destroyed, only transformed.

Applications:
- Internal Combustion Engines: Designing engines that convert fuel into mechanical energy efficiently.
- HVAC Systems: Developing systems for heating, ventilation, and air conditioning that manage heat transfer to maintain comfortable environments.
- Power Plants: Creating and optimizing systems for generating electricity through heat energy.
Fluid Mechanics
Overview:
- Fluid mechanics deals with the behavior of liquids and gases in motion and at rest. It is essential for designing systems involving fluid flow.
Key Concepts:
- Fluid Properties: Understanding viscosity, density, and pressure, which influence how fluids flow and interact with surfaces.
- Flow Dynamics: Analyzing how fluids move through different environments, including laminar and turbulent flow.
- Hydraulics and Pneumatics: Designing systems that use liquid (hydraulics) or gas (pneumatics) to transmit force and motion.
Applications:
- Pipeline Design: Ensuring efficient transport of fluids in pipelines for water, oil, or gas.
- Aerodynamics: Improving the design of vehicles and aircraft to reduce drag and enhance performance.
- Pump and Fan Design: Creating efficient systems for moving fluids or air in industrial and residential applications.
