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 and 0 < S < 150 g/kg;
ACCURACY: 1.5
