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.

Freshwater density

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

S = 35000 mg/l = 35 ‰
