Hydrogen gas volume calculation
Thread Content
The pressure of the circulating hydrogen is 6.7 MPa; how can the volume of hydrogen at this pressure be calculated?
To answer your question, we also need to know the temperature and flow rate of the recycled hydrogen.
6000 NM3/h, 35℃, 95%
Just calculate the molar volume under the actual conditions using the equation of state for real gases; the RK equation or any other equation can be used
Based on the conditions you provided: 6.7 MPa, 6000 Nm3/h, 35°C, 95%, the flow rate under standard conditions is 6000 Nm3/h, which means that 6000 Nm3 passes through the pipeline in one hour. Do you want to calculate the volume flow rate under these operating conditions? Calculations are performed using P1V1/T1=P2V2/T2. . .
You can do well under low pressure, but the error is relatively large under high pressure
The poster said it’s difficult to calculate the volume, as everything is inside the pipelines. The fluid flows in the container, and it is compressed as well. .
