Question:
Ram efficiency is defined as
Ram efficiency is defined as
Show Hint
Understanding ram efficiency is important in the design of air intakes for high-speed aircraft to maximize engine performance.
Updated On: Feb 7, 2025
- Real local temperature rise / ideal temperature rise
- Actual rise in static pressure / ideal rise in static pressure
- Actual total temperature rise / ideal total temperature rise
- Real total pressure rise / ideal total pressure rise
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Definition of Ram Efficiency.
Ram efficiency in the context of air intakes for jet engines refers to the efficiency of converting the kinetic energy of incoming air into pressure energy.
Step 2: Correct Expression for Ram Efficiency.
It is typically defined as the ratio of the real total pressure rise to the ideal total pressure rise, reflecting how effectively the inlet captures dynamic pressure and converts it to static pressure, which can be used by the engine.
