Equation of state of water and sea water

The P-V-T data on water by Amagat and Kennedy et al. and on sea water by Newton and Kennedy, the compressibility data on water by Diaz Pena and McGlashan, the bulk compression data on water and sea water by Ekman, and the sound velocity data on water and sea water by Del Grosso and Wilson have been analyzed using the Tait and the Tait-Gibson equations. The P-V-T relationship for water can be well represented by the Tait equation, V0(P) = V0(1) - C × log [(B + P)/(B + 1)], and for sea water by the Tait-Gibson equation, V(P) = V(1) - (1 - S × 10−3) × C log [(B* + P)/(B* + 1)] where C = 0.315 × V0(1) and B = 2668.0 + 19.867t - 0.311t² + 1.778 × 10−3t³, for Amagat data in the range of 0 ≤ t ≤ 45°C and 1 ≤ P ≤ 1000 bars and B* = (2670.8 + 6.89656 × S) + (19.39 - 0.0703178 × S)t - 0.223t² for Ekman's sea water data in the range of 0 ≤ t ≤ 20°C, 1 ≤ P ≤ 1000 bars, and 30 ≤ S ≤ 40‰.
