Question:
For a given chamber pressure, the thrust of a rocket engine is highest when
For a given chamber pressure, the thrust of a rocket engine is highest when
Show Hint
Lower external pressure increases rocket nozzle exit velocity and thrust.
Updated On: June 02, 2025
- the rocket is operating at its design altitude
- the rocket is operating in vacuum
- the rocket is operating at sea-level
- there is a normal shock in the rocket nozzle
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Rocket thrust is maximized in a vacuum since there's no atmospheric back pressure acting against the exhaust gases.
