Use the linear equation of state of seawater to calculate the density of freshwater (0 salinity) and ocean water (35 salinity) at 15C and zero pressure (relative to sea level pressure).
Given equation : p - pr = a * ( T - Tr ) + b* ( S - Sr ) + k * P
Density of freshwater p = a * ( T - Tr )+b* ( S - Sr ) + k * P + pr
Density of freshwater p = - 0.15 * ( 15 - 10 ) + 0.78 ( 0 - 35 ) + 0.0045 * 0 + 1027
Density of freshwater p = -0.75 - 27 .3 + 0 + 1027
Density of freshwater p = 998.95 kg / m3
Density of ocean water p = a * ( T - Tr )+b* ( S - Sr ) + k * P + pr
Density of ocean water p = - 0.15 * ( 15 - 10 ) + 0.78 ( 35 - 35 ) + 0.0045 * 0 + 1027
Density of ocean water p = -0.75 + 1027 = 1026.25 kg / m3
Use the linear equation of state of seawater to calculate the density of freshwater (0 salinity)...
"Oceanographers are not so much interested in the absolute density of the water but in density changes in space and time. Such changes are quite small. Oceanographers therefore use the quantity_0 = p - 1000 (pronounced sigma-tee = density minus 1000), which gives the density excess or deficit against a reference density of 1000 kg m3. In principle, Ot should have the same unit as p (kg m-3); but oceanographers never give units with ot. Thus, freshwater has a Ot...
