What other important property of a liquid do hydraulic machines depend?

i think it also depends on it's weight of course


What is the basic idea behind hydraulic machines?

The incompressibility of most liquids.


Difference between hydraulics and pneumatics?

hydraulic is liquid based, pneumatic is air.


Why hydraulic oil incompressible?

it is the property of the liquids. all the liquids are incompressible. this is because the change in volume due to pressure is negligible for liquids. in liquids the molecules are almost compact and hence no space for compression.


Why is the fluid in an hydraulic machine a liquid than a gas?

Fluid in hydraulic machines is a liquid because liquids are incompressible, providing consistent pressure transmission. Gases are compressible, leading to fluctuations in pressure and less reliable operation in hydraulic systems. Liquids also offer better lubrication properties and durability for hydraulic components.


Why is the fluid in the hydraulic machine liquid rather than gas?

Fluid in hydraulic machines is typically liquid because liquids are incompressible compared to gases. This property allows the hydraulic system to efficiently transmit force without losing pressure due to compression, resulting in more reliable and precise operation of the machine.


Why can't a gas be used in a hydraulic pipe instead of a liquid?

gasses can compress, so a hydraulic pipe would be useless. In fact, the hydraulic pipe was invented just for water, hence the "hydra" part. Liquids cannot compress, instead they push out, so they are great for machines ( like brake fluid).


Why do hydraulic systems only work with liquids not gases?

Hydraulic systems rely on the incompressibility of liquids to transmit force effectively. Gases are compressible, which would lead to fluctuations in pressure and an inconsistent transmission of force in a hydraulic system. Liquids offer more predictable and stable performance for hydraulic applications.


What is hydraulic efficiency?

Hydraulic efficiency is the rate at which a hydraulic consumes gases and liquids to find different ways to make our lifestyles more efficient.


What liquids are used in hydraulic systems to lift an elephant?

Why are liquids sometimes more practical to use in a hydraulic system than gases?

Because liquids cannot be easily compressed into a smaller space.


What scientific rule do hydraulic systems use?

Generally the incomprehensibility of liquids.
