What is the difference between a closed hydraulic system and an open hydraulic system?

A system which can exchange mass as well as matter with the surroundings is called anopen system.Example:- Heating of CaCo3 in an open bulb.A system which can exchange energy but not matter is called a closed system.Example:- Calcination of CaCo3 in a sealed bulb.


How are input and feedback parts of a system are related?

They are either in closed or in open loop system


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 this food chain an open or closed loop system food chain?

A food chain is typically considered an open loop system because it involves the flow of energy and nutrients from producers to consumers and decomposers, without a closed cycle. In an open system, energy and matter are exchanged with the environment, allowing for continuous input and output. In contrast, a closed loop system would recycle all components without external inputs. Therefore, a food chain represents an open loop system.


Give 3 examples of pneumatic systems?

Pneumatic systems are usually closed systems. Blowing up a party balloon would be one example. A cycle pump would be another, and an air-based system for moving components in pipes would be another. A windmill or a hand fan would not usually be considered to be pneumatic systems because they do not enclose the air component.
