According to Pascal's Law, when pressure is applied to a confined fluid, it is transmitted:
Answer: Equally in all directions
Pascal's Law states that pressure applied to a confined fluid is transmitted equally in all directions throughout the fluid.
What is the primary function of a hydraulic accumulator?
Answer: To store energy and dampen pressure fluctuations
A hydraulic accumulator stores pressurized fluid to dampen pressure spikes and provide supplemental flow on demand.
In a hydraulic system, which component converts mechanical energy into hydraulic energy?
Answer: Pump
A hydraulic pump converts mechanical energy from a motor or engine into hydraulic energy by pressurizing the fluid.
What does a relief valve do in a hydraulic system?
Answer: Limits maximum system pressure to prevent damage
A relief valve limits maximum system pressure by diverting excess flow back to the reservoir when the set-point pressure is reached.
Which type of hydraulic pump uses meshing gears to displace fluid?
Answer: Gear pump
A gear pump traps fluid between meshing gear teeth and the housing, displacing it from inlet to outlet as the gears rotate.
What does viscosity describe in relation to hydraulic fluid?
Answer: The fluid's resistance to flow
Viscosity measures a fluid's resistance to flow, which is critical for pump performance, component lubrication, and system efficiency.
