可以用经验公式计算，参考Thermophysical properties of seawater - MIT，链接地址： http://web.mit.edu/seawater/ 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.
