Question:
When a nozzle is said to be over expanded?
When a nozzle is said to be over expanded?
Show Hint
In rocket engine design, ensuring that the exit pressure matches ambient pressure is crucial for optimal performance and efficiency.
Updated On: Feb 27, 2025
- Pressure at exit is less than the backpressure
- Pressure at exit is higher than the backpressure
- Pressure at exit is equal to the backpressure
- Pressure at exit is equal to zero
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
A nozzle is said to be over expanded when the exit pressure is less than the ambient or backpressure. This condition can lead to flow separation within the nozzle and potentially cause structural and performance issues for rocket engines or jet propulsion systems.
