Challenge Problems
Push your limits with challenges.
Question 1
Consider a Rankine Cycle where the boiler input exergy is measured at 500 kJ and the output exergy after the turbine is 300 kJ. Calculate the exergy destroyed and the efficiency of the cycle.
💡 Hint: Use the exergy balance we've discussed in class.
Question 2
In an effort to improve the Rankine Cycle's efficiency, engineers target the condenser where the exergy loss is at its peak. Discuss the methods that could be employed to minimize this loss.
💡 Hint: Think about how improvements can directly affect the cycle's output and efficiency.
