A rocket nozzle has real kinetic energy changes of 270 J, while the ideal case is 450 J. What is the nozzle's efficiency, and how can it be improved?
💡 Hint: Think about what design changes could be incorporated.
If a diffuser shows a pressure rise of 24 kPa when the isentropic prediction was 40 kPa, evaluate its efficiency and suggest what might cause this discrepancy.
💡 Hint: Consider factors that hinder ideal performance.
