How to convert 1 NM3/h to Kg/h
Thread Content
It is currently known that the inlet temperature of the liquefied gas is 40 degrees Celsius, the inlet pressure is 0.6–0.8 MPa, and the outlet pressure is 0.4 MPa. How to perform the conversion? I hope fellow sailors will share their ideas and suggestions!
If it is X Nm3/h, then it has nothing to do with temperature or pressure; simply use M*X/22.4 to get the value in Kg/h. M is the molecular weight of the component
Is this a liquid or a gas? For gases, the average molecular weight and molar volume of 22.4 are required; for liquids, knowing the density is sufficient.
Measure the density – just multiply the density by the volume!
8 kilograms should be a liquid, so just multiply by the density. When it turns into a gas phase, its mass remains unchanged; m/M*22.4 represents standard cubic units. It’s a simple principle, but it’s important to study it more thoroughly! !
For liquids, multiply by density; for gases, use 22.4
Molecular weight times X squared divided by 22.414 gives the mass flow rate
