Question:

Oxygen leaks slowly through a small orifice in an oxygen bottle. The volume of the bottle is 0.1 m3, and the diameter of the orifice is 0.12 mm. Th e temperature in the tank remains constant at 18°C, and the mass-flow rate is given by m· = 0.68 pA/√RT. How long will it take the absolute pressure to decrease from 10 to 5 MPa?
