Understanding Thermodynamics

• Grasp of the Zeroth Law of Thermodynamics: This law allows us to use temperature as a tool for measuring thermal equilibrium. If two systems are each in thermal equilibrium with a third, then they are in thermal equilibrium with each other.
• Knowledge of the First Law of Thermodynamics: Understanding that energy cannot be created or destroyed, only converted from one form to another.
• Proficiency in the Second Law of Thermodynamics: Acknowledging that total entropy, a measure of the randomness or disorder of a system, can never decrease over time for an isolated system.
• Awareness of the Third Law of Thermodynamics: Realisation that the entropy of a system approaches a constant value as its temperature approaches absolute zero.

Thermodynamic Systems in Engineering

• Familiarity with Closed, Open, and Isolated Systems: Recalling that closed systems can exchange energy (but not mass) with their surroundings, while open systems can exchange both energy and mass, and isolated systems neither.
• Comprehending different Processes like Isochoric, Isobaric, Isotropic and Adiabatic processes and their impact on different system conditions.
• Grasping Heat Engines, Refrigerators, and Heat Pumps: Understanding how these devices that convert energy between heat and work operate.
• Understanding the Carnot Cycle: Recognising the theoretical maximum efficiency any heat engine can achieve while operating between two thermal reservoirs at different temperatures.

Thermodynamics in Engineering Design

• Significance of Entropy Generation and Energy Dissipation: Exploring the impacts of entropy generation (i.e., energy dissipation) on the performance of engineered systems.
• Significance of Efficiency and Performance : Understanding the effects of thermodynamic efficiency and performance margins in engineering design, in terms of both energy resources and economic factors.
• Mastery of Thermodynamic Analysis: Being able to anticipate and interpret the effects of changing conditions on the performance of thermodynamic systems.

Environmental Considerations in Thermodynamics

• Understanding the effects of Energy Conversion on Environment: Comprehending the consequences of releasing heat into the environment from energy conversion systems.
• Realisation of Sustainable Energy Practices: Understanding and appreciating the need for sustainable practices in the use of energy resources.
• Application of Heat Recovery and Waste Minimisation Principles: Incorporating energy recovery and waste minimisation in thermodynamics-based design principles due to their environmental significance.

Safety Considerations in Thermodynamics

• Awareness of Safety Standards in Thermodynamics: Understanding the standards and regulations in place for safety in thermodynamics-based designs.
• Emphasis on Risk Assessment: Evaluating potential hazards associated with thermodynamic systems and taking steps to mitigate them.
• Knowing First Aid Procedures for Thermodynamics Accidents: Understanding what to do in the event of a thermal burn or related incident.
