Question: kgmole/h
Thread Content
Kilogram, mole, per hour – what are these units and how should they be understood? If I have the following data: molar flow rate, kmol/h: 67.4; mass flow rate, kg/h: 1097; density, kg/m3: 1.99, how do I convert this to kgmole/h?
Is the poster using the Hysys software? This unit is the one used in Hysys. We know that the unit of molecular mass is mol, so when a parameter with this unit is multiplied by the relative molecular mass, the result is the mass flow rate! Discussing mass flow rate (kg/h) and molar flow rate (kmol/h) further, in fact, we divide the mass flow rate (kg/h) by the molar mass (not the relative molecular weight, but the actual value of the relative molecular weight in g/mol), thereby obtaining the molar flow rate (kmol/h).
There seems to be a discrepancy between the kmol/h value on the upper floor and the kgmol/h value given by the original poster? ? ?
kgmole/h should be kmol/h, right?
In HYSYS, kgmole/h * molecular weight = kg/h
I still think this one is more reliable
kmol/h=============kgmol/h
I wonder if they are indeed equal; I’ve encountered a similar problem as well
Answer it yourself – they are equal
Sun Lanyi also believes in the books that they are equal
