Question:
The optimum expansion in the nozzle occurs when
The optimum expansion in the nozzle occurs when
Show Hint
Optimum expansion ensures no residual pressure loss or shock formation.
Updated On: June 02, 2025
- exit pressure of the nozzle is greater than the atmospheric pressure
- exit pressure of the nozzle is less than the atmospheric pressure
- exit pressure of the nozzle is equal to the atmospheric pressure
- exit pressure is zero
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Optimal expansion occurs when nozzle exit pressure matches atmospheric pressure, maximizing thrust and minimizing pressure drag.
