The steel thick-walled cylinder, whose volume is equal to V, is filled with oil and is tightly closed at atmospheric pressure. How much oil should be pumped into the balloon in addition, so that the pressure in it increases 25 times? The bulk modulus of oil is E = 1280 MPa. Deformation of the cylinder walls is neglected.
Given: V = 36 dm3 = 0.036 m3; E = 1280 MPa = 1280 * 106Pa; p / p0 = 25; p0 = paT = 105 Pa
