SigmaT | R Documentation |

The function `SigmaT(Temp,digits=9)`

computes the Surface Tension [ mN m-1 ]
for a given Temp [K], returning the calculated Surface Tension and an
error message, if an error occur. errorCodes

```
SigmaT(Temp, digits = 9)
```

`Temp` |
Temperature [ K ] |

`digits` |
Digits of results (optional) |

This function calls a Fortran DLL that solves the equations developed by the International Association for the Properties of Water and Steam, valid from the triple point to the critical temperature [ 273.13K to 647.096K]. http://www.iapws.org/relguide/Surf-H2O.html

The Surface Tension: Sigma [ mN m-1 ] and an Error Message (if an error occur)

```
Temp <- 500.
Sig <- SigmaT(Temp)
