Concept

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:

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