Engineering Thermodynamics
Thermodynamics is bookkeeping with a direction attached: the first law says the books must balance, the second says which way the entries can go. These topics animate the boundary and the flows across it.

Foundations
Systems, boundaries, properties and states — the vocabulary everything else is written in.
- Properties, state and equilibrium
- Processes and cycles
- Zeroth law and temperature scales
- Work and heat as boundary interactions
The first law
Energy is conserved — applied to closed systems, then to flows.
- First law for a closed system
- Internal energy and enthalpy
- Specific heats
- Steady flow energy equation
- Applications: nozzles, turbines, compressors, throttles
The second law
Why energy being conserved is not enough to make it useful.
- Kelvin-Planck and Clausius statements
- Heat engines, refrigerators and COP
- Carnot cycle and Carnot efficiency
- Clausius inequality
- Entropy and the principle of increase
- Availability and irreversibility
Properties of pure substances
Steam tables, and what a phase diagram is actually recording.
- Phase change and the p-v-T surface
- Dryness fraction and steam tables
- Mollier diagram
- Ideal gas and real gas equations
Power and refrigeration cycles
The arrangements engineers actually build.
- Otto, Diesel and dual cycles
- Brayton cycle
- Rankine cycle and reheat/regeneration
- Vapour compression refrigeration
- Psychrometry
