Aw = h0 + h1t + h2t2 + h3t3
h0* = + 3.239908 [- 0.1194975]
h1 = + 1.43713 E-3
h2 = + 1.16092 E-4
h3 = - 5.77905 E-7
Bw = k0 + k1t + k2t2
k0* = + 8.50935 E-5 [+ 3.47718 E-5]
The E0S80 is valid for S = 0 to 42; t = -2 to 40℃; p = 0 to 10000 decibars.
The following values are provided (Unesco Report No.38 p.191) for checking the correct use of the above equation. The density anomaly can be compared directly with p (S, t, p) when 1000. kg/m3 is added. Differences in the last decimal place particularly of specific volume can be expected due to round-off. (Units of p are kg m-3 and V m3/kg.)
