stdvol definition in ASPEN
Thread Content
Stdvol, used as a basis for stream flow on this sheet, refers to standard liquid volume, which is defined at 1 atmosphere and at a temperature of 60°F by default. Click the Ref Temperature button to set a different reference temperature for calculations related to standard liquid volume flow, mass concentration, or mole concentration. To specify flows in terms of standard vapor volume, choose the Mole basis and select units such as scfm (standard cubic feet per minute) or scmh (standard cubic meters per hour). The standard conditions for standard vapor volume depend on the units chosen; for standard cubic feet, these conditions are 14.696 psia and 60°F, while for standard cubic meters they are 1 atm and 0°C. In both cases, the standard flow assumption is that the gas behaves as an ideal gas.
Thank you, OP; I’ve learned something from this. I’ve been struggling with this issue. I’d like to ask gently: is the source of this section the user guide or the reference manual?
