Which outcome results when jet fuel viscosity increases excessively in an airliner's fuel system?

A)Reduced fuel pump cavitation erosion
B)Enhanced compressor blade heat transfer
C)Decreased injector nozzle atomization
D)Improved laminar boundary layer thickness

💡 Explanation

Reduced injector nozzle atomization results because increased fluid viscosity leads to higher surface tension, creating larger droplets during 'atomization'. Therefore, larger, less-combustible droplets mean less efficient combustion, rather than A/B/D since they depend significantly less on viscosity.
