  4. COMPRESSIBILITY AND BULK MODULUS OF ELASTICITY In case of hydraulic systems the working fluid is incompressible (density constant) fluid (water, oil, mercury,etc) subjected to external pressures causing the change in volumetric strain (decreased) or increased density strain due to the fluid behaviour compressibility as shown in fig.
