A mixture is composed of 3% air and 97% hydraulicfluid by volume. It llsa 20 cm3 container, and is initially at atmospheric pressure. The top of the container is compressed until the fluid pressure becomes 1 MPa absolute. The air adheres to the ideal gas law, and the compression is isothermal at 25C. The bulk modulus of the oil is known to be oil = 1.9 GPa.
What is the compressed volume of the mixture?
