The **Tait equation** is an equation of state. The equation was originally published by Peter Guthrie Tait in 1888. (Yuan-Hui Li, 15 May 1967, Equation of State of Water and Sea Water, Journal of Geophysical Research 72 (10), p. 2665.) It may be written as

or in the integrated form

where

- is the compressibility.
- is the specific volume.
- and are functions of temperature that are independent of pressure.
