For a pipeline with a volume of 5000 cubic meters, which is already filled with nitrogen at a pressure of 1.6 Mpa, and the pressure is to be increased to 2.5 Mpa, how many cubic meters of nitrogen are required? I would appreciate it if someone could explain how to calculate this
Can the ideal gas law pv=nRT be used?
5000*（25-16）=45000m3
The amount of nitrogen that can be stored in a 5000 m³ pipeline at a pressure of 2.5 MPA, minus the amount of nitrogen stored at a pressure of 1.6 MPA, equals the amount of nitrogen that needs to be replenished. You haven’t provided the pipe temperature; it is currently assumed to be 0 degrees. If the temperature was 20 degrees at that time, the gas consumption would be lower, by about 20/293.
Could you tell me which formula is being used? Thank you
P mark V mark/T mark = PV/T; temperature is in K scale
For gases, PV=nRT; the ideal gas equation can be used at low pressures. Low pressure
