Learning Outcomes
1. Analyse thermodynamics principals for temperature, pressure, gas laws, thermal expansion, conservation of energy, change of phase, heating and thermal efficiency.
2. Apply thermodynamics principals to practical applications for refrigeration, heat exchanger, and solar collectors.
3. Calculate rates of heat transfer through multiple layers and combined modes.
4. Evaluate and compare the sources of energy in NZ including sustainability concepts.
