← ScienceWhich outcome results involving hydraulic servo valve when Reynolds number drops too low?
A)Increased flow-induced valve spool instability
B)Laminar flow dominates valve operation✓
C)Elevated amplification of control signals
D)Cavitation of servo fluid decreases
💡 Explanation
Laminar flow dominates valve operation because at low Reynolds numbers, inertial forces are less significant, permitting viscosity to dominate, therefore flow becomes smooth rather than turbulent which hinders valve responsiveness rather than increases spool instability under stable conditions.
