What I have experienced so far Nm3/hr is the volume flow considered at 0°C and 1 bar (absolute).
Sm3/hr is the flow taken at 15°C and 1 atm (1,013 barA).
However, the 15°C is sometimes subjected to dicussion: 20°C is taken as well.
Conversion can easily be made by using (P*V)/T = C

You can try www.hyprotech.com or www.aspentech.com.
But assuming you are using version 3.2 there must be some pdf file (called "menu.pdf"?)which leads you through the principals of Hysys. You can probably execute this file by going to Hysys in the start menu of windows.
good luck, Kingsss
In order to evaluate the necessity of noise reduction measurements in a PSV/tailpipe system, I am looking for information to estimate the potential noise absorption of the tailpipe.
So far, I only found a rule of thumb: - 3dB/50D_pipelength, without any reference or description. However, I...
"chemical engineering Vol 1", by Coulson & Richardson (university of Swansea, UK)can help you out with all sorts of heat transfer calculations.
You might wanna look on www.tycothermal.com (a.o. supplier of Raychem heat tracing) as well.

I'm looking for a formula/correlation which describes the relation between the diameter of a tail pipe (or velocity of gas leaving the tail pipe) and the production of sound.
Considering a Pressure Relief Valve system, I need this relation in order to caclulate the minimum internal diameter of...
