# Problem: Hydraulic fluid is compressed by a piston in a cylinder producing a change in pressure of 120 MPa. Before the piston is activated, the hydraulic fluid fills a 16cm length of the cylinder. If the axial displacement of the piston is 8mm, what is the bulk modulus of the hydraulic fluid?

###### FREE Expert Solution

The expression for the bulk modulus is:

$\overline{){\mathbf{B}}{\mathbf{=}}\frac{\mathbf{∆}\mathbf{P}}{\mathbf{\left(}\mathbf{∆}\mathbf{V}}{\mathbf{V}}\mathbf{\right)}}}$
