The volume of a cylinder equals the area of the base times the height, which equals pi x radius squared x height. Inserting the numbers, V = pi x (2 m.) squared x 5 m. = pi x â¦4 m. squared x 5 m. = 20 x pi meters cubed or 20 x pi cubic meters.
How to calculate the amount of gas in a compressed cylinder up vote 4 down vote favorite I am trying to calculate a cost per hour use of a gas we buy in a cylinder. The details I have been working with are: Gas used CP-grade N2 material number: 110628-L can. Gas: N, density = 1.251 g/L @ 0.101 MPa M (molar mas) = 14.007; Gas cylinder: Pressure = 200 bar or 20 MPa Cylinder volume 9.45 m3 or 9450 L Operating pressure of gas from cylinder = 4.5 bar or 0.45 MPa and flow rate = 60 cL/min I have been applying the ideal gas law to PV=nRT to figure out how many total litres of N are in the can at 4.5 bar pressure to then get a rough estimate of how many hours of flowing gas I get.
