Study Notes
Heat Engine Components
- A heat engine has three main parts: heat source, working substance, and heat sink
- Heat source (T1K): provides heat to the working substance
- Working substance: converts heat into work
- Heat sink (T2K): absorbs waste heat from the working substance
Heat Engine Processes
- Heat is absorbed from the heat source, converting some into work.
- The remaining heat is expelled to the heat sink.
- Net work done = heat absorbed - heat expelled
- Q1 = heat absorbed from source
- Q2 = heat released to sink
- W = net work done
Heat Engine Efficiency
- Efficiency = (Work output) / (Heat input)
- Efficiency = (Q1 - Q2) / Q1
