Which consequence results when fluid viscosity is abnormally low in a hydraulic service valve?

💡 Explanation

Increased internal valve leakage results from reduced viscosity because the laminar resistance to flow decreases; therefore, clearances allow fluid to escape, rather than be directed, different to high viscosity inducing sluggishness within similar tolerances.
