Problem

A hydraulic press uses oil with bulk modulus

B = 1.6\times10^{9}\,\text{Pa}

. During operation, the pressure in the oil increases by

\Delta P = 5.0\times10^{6}\,\text{Pa}

. If the oil were assumed incompressible, its density would be treated as constant. What is the actual percentage increase in the oil’s density caused by the pressure rise? a) 0.50\% b) 0.31\% c) 0.80\% d) 0.16\%
