Determine the change in the volume of industrial oil enclosed in a steel cylinder under atmospheric pressure when the pressure increases to 20 MPa. The length of the cylinder is 1 m, the internal diameter d = 100 mm, the thickness of the cylinder wall d = 1 mm, the elastic modulus of the oil Ezh = 1700•106 N/m2, the elastic modulus of the pipe material Et = 2•105 MN/m2.
