Question 1.
What is the purpose of superheating in power cycles?
Show hintHide hint
Think about energy extraction.
Question 2.
Define regeneration.
Show hintHide hint
This involves recycling some of the steam.
3Question 3.
What process increases the average temperature of heat addition in steam cycles?
- Superheating
- Condensation
- Isentropic Expansion
Show hintHide hint
It's related to how heat is added!
4Question 4.
True or False: Regeneration improves efficiency by recycling waste heat.
- True
- False
Show hintHide hint
Think about using previously used energy.
Question 5.
A steam power plant functions with a basic Rankine cycle at a thermal efficiency of 30%. After integrating superheating and regeneration, efficiency rises to 45%. Calculate the percentage improvement.
Show hintHide hint
Calculate the difference first before dividing by the old efficiency.
Question 6.
Discuss how minimizing exergy destruction in a Rankine cycle can lead to more sustainable energy practices.
Show hintHide hint
Focus on long-term energy implications and environmental impacts.
