← ScienceWhich consequence results when hydraulic fluid viscosity increases at low temperatures?
A)Increased volumetric efficiency occurs
B)Decreased pump cavitation risk happens
C)Reduced actuator response arises✓
D)Improved thermal dissipation begins
💡 Explanation
Reduced actuator response arises because increased fluid viscosity increases the fluid's resistance to flow through narrow passages, thereby decreasing the speed and force transmitted to the actuator via momentum diffusion. Therefore the response slows, rather than improving volumetric efficiency under these conditions.
