← ScienceWhich limiting consequence results when hydraulic fluid viscosity decreases in heavy machinery?
A)Increased component wear rate occurs✓
B)Reduced system bulk modulus results
C)Elevated fluid oxidation accelerates
D)Decreased thermal expansion happens
💡 Explanation
Increased component wear occurs because viscosity reduction lowers hydrodynamic lubrication via the Petroff equation; therefore, metal-on-metal contact increases, rather than oxidation or thermal effects, and bulk modulus represents fluid compressibility under applied pressure.
