Dear Dr. Panda,
the note on Saturday was a quick
shoot and I forgot to mention
that the saturation vapor
pressure in the psychromter
equation ES (step 4) should
be determined from wet-bulb
temperature Tw (step 3)
EA=ES(Tw)-gamma*pa*(Ta-Tw)
and those for calculating
humidity (step 5) from
dry-bulb temperature (step 2)
hr=EA/ES(Ta)
Sorry for the confusion you and
others might have had.
Matthias
