Is a piston pump hydraulic or pneumatic?
both, if it pumps liquid then it's hydraulic, if it pumps gas it is pneumatic
What is a pneumatic bike pump?
it is a bike operated by air
What does hydraulic and pneumatic systems have incommon?
both pneumatic & hydraulic systems are applications of fluid powers
Is a backhoe loader hydraulic or pneumatic?
its hydraulic.
Are Dam hydraulic or pneumatic?
It depends on the dam. Some dams are hydraulic and some are pneumatic. Short answer: Both
Are all cranes hydraulic?
It may be hydraulic or pneumatic system
How does a pneumatic differ from hydraulic system?
Transmission fluid is performed by the hydraulic system. Pneumatic power transmission system is done by the gas.
How is hydraulic system better than pneumatic system with a brief disicussion?
Difficult question to answer without context. Key thing to understand is a pneumatic system uses a compressor, whereas a hydraulic system uses a pump. Hydraulic fluid is essentially incompressible, whereas compressed air will fill any volume. Ask yourself: What is my pneumatic/hydraulic system supposed to do? How fast should it react and what horsepower is available to drive my compressor/pump? What force do I need at my actuator/motor or whatever the system is expected to power? Generally, I think pneumatic systems can react more quickly but power density is lower, so if the load is very high a hydraulic system might be better. A typical shop pneumatic system might only operate at 50psi, whereas a hydraulic system can operate at 3000psi. Finally, it's also worth thinking about system safety: if a pneumatic component fails, there will be an explosive decompression, but if a hydraulic component fails, it will leak but will not explode because hydraulic fluid does not store energy, it only transmits it.
Are flap controls on an airplane hydraulic or pneumatic?
They are hydraulic. Most controls surfaces are hydraulic.
What are the fluids used in pneumatic and hydraulic systems?
Pneumatic systems use air or an inert gas. Hydraulic systems use water or oil.
What are some examples of pneumatic devices?
Yes there is. Pneumatic valve springs. They are metal bellows that have air in them. Their use is in replacing metal wire springs in a high-speed combustion engine. An example would be formula one engines.
Is an internal combustion engine hydraulic?
no its pneumatic.
