How to calculate gas volume
Thread Content
Please tell me how to calculate "If a 106m³ hydrogen storage tank with a working pressure of 1.1MPa is used as a gas source tank and supplies 0.5MPa gas to the system, how much standard cubic volume can be provided before the hydrogen storage tank pressure is reduced to 0.5MPa? ”It would be best to know the calculation process, thank you very much!
Just consider it as an ideal gas. P1V=n1RT P2V=n2RT n1-n2=The hydrogen gas n that can be provided is equivalent to 8.314 * n * 273.15/101325 So many standards.
As an ideal gas, we can directly use the formula: P1V1=P2V2 gets V2 =P1V1/P2=1.1 * 106/0.5
It's very simple, the poster should do it himself.
Calculate P1V1=P2V2 according to ideal gas, P1=1.1MPa, P2=0.5MPa, V1=106m³ and get V2 =P1V1/P2=1.1* The volume of hydrogen gas that 106/0.5 can provide is V=(V2-V1), which can then be converted into the standard state. (You need to know the temperature of the air source)
