ABSTRACT:
Example methods and apparatus to determine the compressibility of a fluid are disclosed. A disclosed example method includes capturing a fluid in a chamber, pressurizing the captured fluid to first and second pressures, measuring first and second values representative of first and second densities of the fluid while pressurized at respective ones of the first and second pressures, and computing a third value representative of a compressibility of the fluid using the first and second values.
