<p><I have seen that it requires to call Psychrometrics Routine, Moist Air Properties and Air Properties. Where can I find these property files? are they standard values and is there any reference for them?></p>
<p>The psychrometrics routine can be found in the source sode/kernel directory and the file is called psych.f90. This routine uses an equation of state to calculate the remaining moist air properties given the known moist air properties. For example, I could call psych with h, T and P and get back the relative humidity and the entropy. The dry air properties can be found in the TESS Libraries\Source Code directory.</p>
<p><The component requires to call data from external file containing ‘InterpolateData’. This InterpolateData gives friction capacity and power for a range of air temperature and water temperature, however I am wondering what will happen when the actual air temperature and/or water temperature is out of the range (how the calculation is carried out)? Is there any correlation used for this scenario? ></p>
<p> </p>
<p>If the values are outside the range, the value at the end of the range is used - no extrapolation is done. The documentation for InterpolateData can be found in the documentation folder.</p>
