Hi
I know that PI Performace calculations includes the ability to get Steam table data. Ethalpy, entropy, Saturated steam etc etc.
could one of the more knowledgable person assist me with getting the correct formats
I have managed by Trial and error to get the following working
stmSi_PsatT this seems to give steam saturation pressure with temerature as is basis. .
for example
StmSI_PsatT(100)
will return a value of 101.325275 the result must be in Kn/M3 as for absloute pressure in bar it should be 1.013 for mbar 1013 etc.
The value in brackets can be any suitable Tag from the server
does anyone know what the units are for the stmSI expressions are, and howmany variant of stmSI/stmENG are there?
google is not very helpfull today
any help would be very welcome.
