← ScienceWhich outcome will occur when exceeding mass flow limits in a gas turbine?
A)Rotational speed decreases uncontrollably
B)Compressor surge, engine instability results✓
C)Thermal efficiency temporarily increases
D)Fuel consumption linearly decreases
💡 Explanation
Compressor surge occurs because exceeding mass flow limits reduces the effective incidence angles; therefore, the boundary layer separates, and pressure oscillations cause engine instability rather than efficient burning.
