The Tait equation is an equation of state. The equation was originally published by Peter Guthrie Tait in 1888 [1][2]. It may be written as

or in the integrated form
- Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle V = V_0 - C \log \frac{B+p}{B+p_0}}
where

It is quite common that this name is improperly used for the adiabatic form of the stiffened equation of state.
