Hydraulic oil compressibility, what is it and what are the ...

Jan 27, 2020· In other words, the dissolved air decreases the bulk modulus of mineral oils and therefore decreases the resistance to compression. This effect is especially present at low operating pressures, as a fluid is pressurized, the entrained air is compressed and has less influence on the compressibility.

A simple relationship between isothermal bulk modulus and ...

Sep 27, 2005· The variations in isothermal bulk modulus with an increase in temperature are found to be related linearly with the change in thermal pressure for geophysical minerals, such as MgO, CaO, Al 2 O 3, MgAl 2 O 4 and Mg 2 SiO 4.Analysis of the relationship yields a value of the Anderson–Gruneisen parameter for each mineral in close agreement with known values.
