Oxygen Cylinder
A standard cylinder of oxygen used in a hospital has gauge pressure = 2000 psi (13,800 kPa) and volume = 17 L?
A standard cylinder of oxygen used in a hospital has gauge pressure = 2000 psi (13,800 kPa) and volume = 17 L (0.017 m^3) at T = 295 K. How long will the cylinder last if the flow rate, measured at atmospheric pressure, is constant at 2.8 L/min?
_________________hr
Pc Vc / (RTc) = n = Patm Q t / (RTatm)
Tc = Tatm
then (2000psi = 136.09 atm)
t = Pc Vc / (Patm Q ) = 826 min = 13h 46 min
