Questions regarding the calculation of gas flow rate and discharge volume

2017-05-09View Original

Thread Content

I would like to ask fellow sailors: if there is a sealed container containing carbon dioxide gas at a pressure of about 0.2 MPa, and an exhaust hole is provided in it, how many kilograms of gas will be expelled in a time period of t? (A gas pipeline ensures a constant pressure inside the container). If the opening is connected to a small container with a volume of V, and after the small container is evacuated the opening is opened, how long does it take for the two containers to reach equal pressure? (assuming a vacuum level of -0.09).
