Fluid Systems Quiz

What is the main difference between a pneumatic system and a hydraulic system?

• The main difference is the medium used: pneumatic systems use compressed air, while hydraulic systems use fluid (usually oil).

• The main difference is the temperature range: pneumatic systems operate at higher temperatures, while hydraulic systems operate at lower temperatures.

• The main difference is the size of the components used: pneumatic systems are smaller, while hydraulic systems are larger.

• The main difference is the color of the components used: pneumatic systems are red, while hydraulic systems are blue.

Explain the working principle of a basic pneumatic system.

• A pneumatic system uses water instead of air for energy transmission.

• The working principle of a pneumatic system involves the use of magnets to control energy flow.

• Pneumatic systems rely on electrical signals for operation.

• A basic pneumatic system works by using compressed air to transmit and control energy through components like valves, cylinders, and actuators.

Describe the components of a hydraulic system.

• Reservoir, pump, valves, actuators

• Tank, compressor, gears, sensors

• Hose, gauge, solenoid, accumulator

• Cylinder, filter, motor, pipes

What are some common troubleshooting techniques for fluid systems?

• Using incorrect pressure settings

• Not checking for leaks

• Ignoring fluid levels

• Checking for leaks, inspecting valves and fittings, verifying fluid levels, ensuring proper pressure, and cleaning or replacing filters.

How can you identify faults in a pneumatic system?

• Hit the components with a hammer

• Follow steps to check for leaks, inspect connections, verify pressure gauges, test components, and consult manuals or professionals if needed.

• Smell the air for leaks

• Ask a psychic for guidance

Explain Pascal's law and its application in fluid systems.

• Pascal's law states that pressure in a fluid decreases with depth

• Pascal's law is the principle that a change in pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and to the walls of its container. It is applied in hydraulic systems to create mechanical force by utilizing the transmission of pressure in confined fluids.

• Pascal's law is only applicable in gaseous systems

• Pascal's law does not apply to hydraulic systems

What is the perfect gas law and how is it relevant in fluid systems?

• The perfect gas law is PV = nRT and it is relevant in fluid systems for analyzing solid behavior.

• The perfect gas law is PV = nRT and it is relevant in fluid systems for analyzing liquid behavior.

• The perfect gas law is PV = nRT and it is relevant in fluid systems for analyzing electromagnetic behavior.

• The perfect gas law is PV = nRT and it is relevant in fluid systems for analyzing gas behavior.

What is the formula for calculating pressure in a fluid system?

• pressure = density * height

• pressure = mass * acceleration

• pressure = force / area

• pressure = volume / area

How does temperature affect the behavior of gases in a pneumatic system?

• Higher temperature decreases pressure and volume of gases in a pneumatic system.

• Temperature only affects the color of gases in a pneumatic system.

• Temperature has no effect on gas behavior in a pneumatic system.

• Temperature affects the kinetic energy of gas molecules, leading to changes in pressure and volume according to the ideal gas law.

What are some common issues that can arise in hydraulic systems?

• Rust formation, electrical issues, air contamination

• Leaks, fluid contamination, overheating, pump failure
