Bulk Modulus - Lee IMH

The bulk modulus and the coefficient of cubical thermal expansion can be used together to compute the pressure rise in a closed system subjected to an increasing temperature. EXAMPLE: MIL-H-83282 oil at 0 psi is heated from 70°F to 120°F in a closed, constant volume system containing 100 cu. in.

Bulk modulus - HAWE Hydraulics India

The size of the bulk modulus for air-free oil at 50 C is around 1.5 · 105 N/cm2. Air in the form of bubbles reduces the bulk modulus significantly (at least for pressures under 200 bar). In practice therefore, the bulk modulus is often 1.0 to 1.2 x 105 N/cm2 (see also
