Which outcome results when hydraulic fluid viscosity shifts excessively?

A)Increased pump cavitation wear rate
B)Decreased actuator response time linearly
C)Elevated system power transformation efficiency
D)Reduced valve turbulent transition threshold

💡 Explanation

Increased pump cavitation wear occurs, because reduced viscous damping impairs lubrication, leading to greater frictional heating initiating vapor bubble formation, therefore cavitation, rather than increased efficiency with optimized viscosity; increased viscosity usually has effects reverse to options B/D.
