← ScienceWhich outcome occurs when hydraulic fluid viscosity decreases within machinery?
A)Increased internal leakage across components✓
B)Reduced fluid bulk modulus degradation
C)Higher pressure energy intensifies resistance
D)Improved sealing performance within actuators
💡 Explanation
Decreased viscosity allows increased internal bypass, because there is reduced resistance to flow through small clearances within hydraulic components. Therefore, internal leakage increases, rather than improving sealing, because lower viscosity offers less resistance.
