Helium, as it's gas at room temperature.
oil bp is there
A gas may not be suitable to fill the tube that moves the piston in the rubbish-mover if it is compressible and exhibits significant changes in pressure with temperature variations. Compressible gases can lead to inconsistent and unpredictable movement of the piston, impacting the efficiency and control of the rubbish-mover. In contrast, using a non-compressible fluid like a hydraulic oil would provide more stable and reliable operation of the piston in the rubbish-mover system.
Helium is created by the radioactive decay of certain elements in the earth's crust. ---- Oil wells is a common source of helium. Some people worry that we may have future shortages of helium as the supplies in wells is used/released.
Helium, but there are more limited supplies of it. At the time of the Hindenburg, the US was the sole source with all of it coming from Texas oil fields mixed in with the natural gas. It was there because of the combination of deep Uranium Ore deposits and Salt Domes, Uranium decay alphas captured electrons becoming Helium then got caught in the salt domes with the natural gas on top of the oil. The US refused to sell Helium, a strategic resource to Nazi Germany. Helium is a Nobel Gas thus inert, Hydrogen ignites and burns easily.
Most fluids are not very compressible at all. I doubt there are any fluids, flammable or not, that are much more compressible than water. Maybe 50% more compressible (at best a factor of 2), but I very much doubt there are fluids that are 3-4 times as compressible as water. Gases on the other hand are very compressible. Solids and liquid not so much.In general, organic solvents tend to be more compressible than water. See the Web Links for some values and other information. It looks like ethanol is about twice as compressible as water, although it is flammable, and so is carbon disulfide, but that is also flammable.From the original questioner: According to the CRC Handbook, ethyl ether has a bulk modulus of around 15e-6 per dbar re: water at 4.4 e-6 per dbar; so that is about 4 times but this is both the ether of anesthesia fame as well as volitile and flammible i'm after some 'magic fluid' with even better compressibility (5 to 10 times) and not so dangerous, i guess it doesn't exist! thanks! Reply: You do realize of course that there are many gases that are both compressible and not flammable. Of course much much harder to contain and deal with, but would easily satisfy the other two requirements... just a thought.
No, because it is not compund substance
water is compressible
oil is slightly compressible 0.5 % at 70 bar. but air is compressible. so to get the required pressure pneumatics require more energy source than hydraulics also there are some limitations for pneumatics in terms of force.
Actually, oil can be slightly compressible. As an oil field is produced and the pressure declines, the oil within the oil deposit will expand. Most liquids, like water, are slightly compressible. This is an important property in the evaluation of oil fields and well testing. See link.
This is because the specific heat capacity of the wood is more than the kerosene oil. So, the wood takes time to burn but burns for longer period than the kerosene oil.
Linseed oil is good for wood as it penetrates the wood fibers, providing protection and enhancing the wood's natural beauty. It helps improve the wood's durability by making it more resistant to moisture, scratches, and wear. Additionally, linseed oil can give the wood a rich, warm finish that enhances its appearance.
Oil, wood, china goodies, and more.
Using motor oil on wood can help preserve it by creating a protective barrier that repels moisture and prevents decay. The oil penetrates the wood, making it more resistant to water damage and extending its lifespan.
Oil transmits power readily because it is minimally compressible, Lubrication abilities and the cooling properties.

more about 70 bucks more actually (i think)
Yes, wood generally floats on oil because it is less dense than oil. The density of wood is lower than that of oil, causing it to float on the surface. Oil is denser and will tend to stay underneath the wood.
