# Seawater - Properties

## Seawater properties like density, saturation pressure, specific heat, electrical conductivity and absolute viscosity.

Seawater temperature, saturation pressure, specific volume, specific heat, electrical conductivity and absolute viscosity. Density calculated for salinity S = 35000 mg/l.

Salinity is normally quoted in units ‰ (parts per thousand):

• S = 35000 mg/l = 35 ‰
