可以用经验公式计算,参考Thermophysical properties of seawater - MIT,链接地址:

SW_Viscosity    Dynamic viscosity of seawater
=========================================================================

  USAGE:  mu = SW_Viscosity(T, S)

  DESCRIPTION:
    Dynamic viscosity of seawater at atmospheric pressure (0.1 MPa) using Eq. (22) given in [1] which best fit the data of [2], [3] and [4].
    The pure water viscosity equation is a best fit to the data of [5].
    Values at temperature higher than the normal boiling temperature are calculated at the saturation pressure.

  INPUT:  (all must have same dimensions)
    T = temperature [degree C] (ITS-90)
    S = salinity    [g/kg] (reference-composition salinity)

  OUTPUT:
    mu = dynamic viscosity [kg/m-s]

  VALIDITY: 0 < T < 180 C; 0 < S < 150 g/kg
  ACCURACY: 1.5%

  REVISION HISTORY:
    2009-12-18: Mostafa H. Sharqawy (mhamed@mit.edu), MIT
                - Initial version
    2015-07-01: Kishor G. Nayar (kgnayar@mit.edu) and
