← ScienceWhich mechanism diminishes hydraulic pump performance at high temperature?
A)Viscosity reduction causes internal leakage✓
B)Fluid density induces cavitation erosion
C)Increased surface tension enhances sealing
D)Thermal expansion overcomes tight tolerances
💡 Explanation
A temperature increase reduces the oil's viscosity. Because decreased viscosity reduces resistance to flow across the pump's internal clearances; therefore, leakage bypasses pumping chambers, rather than achieving intended pressure output, rather than higher system work.
