sw.viscosity {oce}R Documentation

Seawater viscosity

Description

Compute viscosity of seawater, in Pa*s

Usage

  v <- sw.viscosity(S, t);

Arguments

S in-situ salinity [PSU]
t in-situ temperature [degC]

Details

Derived from a curve fit to table 87 of Dorsey (1940). The fit matches the table to within 0.2 percent at worst, and with average absolute error of 0.07 percent. The maximum deviation from the table is one unit in the last decimal place.

No pressure dependence was reported by Dorsey (1940).

It would be a good idea to look for other values to check those used here, and of course to get an idea of pressure dependence. Therefore, this subroutine is provisional.

Value

Viscosity of seawater in Pa*s. Divide by density to get kinematic viscosity in m^2/s.
