Problem

A hydraulic press uses oil with bulk modulus B=1.6×109 PaB = 1.6\times10^{9}\,\text{Pa}. During operation, the pressure in the oil increases by ΔP=5.0×106 Pa\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\%
