Measurements have been made of the extension of a column of liquid water in a centrifugal field. Schlieren photographs of the meniscus position were made at rotational speeds up to 18 000 rpm at temperatures from 5 to 35deg;C. The data were analyzed using a form of the Tait equation. All of the data were able to be represented well within experimental error,7.5times; 10minus;5ccsol;cc. The constants in the equation, found by regression of these negative pressure data, are very nearly those which describe the positive pressure region.
