A large evacuated tank whose volume is 10,000ft3 is to be filled with carbon dioxide gas at atmospheric pressure (14.7psia (lbf/in2). The CO2 is stored in cylinders of volume 2 ft2 at a pressure of 800 pisa (lbf/in2). All this is done at the same temperature.
Assuming CO2 to be an ideal gas how many cylinders will be required?
