gsw_osmotic_pressure_t_exact

`osmotic pressure`

USAGE:

`osmotic_pressure_t_exact  =  gsw_osmotic_pressure_t_exact(SA,t,pw)`

DESCRIPTION:

`Calculates the osmotic pressure of seawater.`
 ```Click for a more detailed description of calculating the osmotic pressure of seawater.```

INPUT:

```SA =  Absolute Salinity                                         [ g/kg ]
t  =  in-situ temperature (ITS-90)                             [ deg C ]
pw =  sea pressure of the pure water side                       [ dbar ]
( i.e. absolute pressure - 10.1325 dbar )```
```SA & t need to have the same dimensions.
pw may have dimensions 1x1 or Mx1 or 1xN or MxN, where SA & t are MxN.```

OUTPUT:

`osmotic_pressure_t_exact  =  osmotic pressure of seawater       [ dbar ]`

EXAMPLE:

```SA =  [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
t  =  [28.7856; 28.4329; 22.8103; 10.2600;  6.8863;  4.4036;]
pw =  [     10;      50;     125;     250;     600;    1000;]```
`osmotic_pressure_t_exact = gsw_osmotic_pressure_t_exact(SA,t,pw)`
`osmotic_pressure_t_exact =`
` 1.0e+002 *`
