What is the difference between traffic stdvol and volume?
Thread Content
I’m just learning the Aspen software, and I don’t know which option to choose when entering the liquid volume flow rate The temperature is 35 degrees; what is the difference between these two? Seeking help online, thank you. This post was last edited by yuyiyummy on 2008-8-25 17:16.]
stdvol is the standard volumetric flow rate, that is, converting Volume into the volumetric flow rate under standard conditions. Volume refers to the volumetric flow rate, that is, the flow rate at the current temperature and pressure; this is usually the value to be used!
Is stdvol converted based on the ideal gas law?
Under the default standard conditions, the gas volume for PROII is 22.414 m3/kmol
stdvol is the standard-state volume, a way of expressing the amount of substance, independent of the actual temperature and pressure it is in； Vol refers to the actual volume, that is, the volume of a fluid under certain temperature and pressure conditions.
Gas STDVOL: 1ATM, 60F or 32F. Liquid STDVOL: 25C or 60F. Agree with the definition of VOL on floor 5
Standard Volume: The standard volume occupied by one mole of vapor at standard temperature and pressure. The default values are: English: 379.49 ft3 per pound-mole at 60°F and 1.0 atmosphere; Metric, SI: 22.414 m3 per kilogram-mole at 0.0°C and 1.0 atmosphere (Metric, SI)
Thank you, I finally understood it: lol
