← ScienceWhich 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.
