← ScienceWhich outcome reduces efficiency in a jet engine?
A)Boundary layer flow destabilization✓
B)Increased compressor blade solidity
C)Higher bypass ratio utilization
D)Decreased nozzle expansion ratio
💡 Explanation
Boundary layer flow destabilization triggers flow separation, initiating stall because adverse pressure gradients overcome the fluid's momentum; therefore, engine efficiency drastically reduces rather than being more efficient with design choices.
