← TechnologyWhich control problem primarily emerges when hydraulic systems experience sudden valve closure?
A)Pressure surge generation (water hammer)✓
B)Thermal expansion exceeding design tolerances
C)Viscosity decreases due to shearing
D)Corrosion accelerates non-linearly
💡 Explanation
Sudden valve closure causes a rapid pressure increase at the valve faces because momentum of the fluid is abruptly stopped, creating a pressure surge called water hammer, rather than thermal expansion or other deterioration occurring at an expected range.
