Which consequence results when a high-speed paint sprayer's nozzle becomes clogged with highly viscous paint fractions?

A)Reduced atomization of the paint
B)Increased paint droplet electrostatic charge
C)Elevated nozzle temperature decreasing viscosity
D)Improved uniformity of deposited paint

💡 Explanation

Reduced atomization occurs because a clogged nozzle increases local pressure, impeding fluid flow; the viscosity of thickened paint fractions further resists breakup via surface tension forces during atomization, therefore atomization is worse rather than better outcomes.
