Volume , (Pi R<2 * L) 1* 3.14 * 5 = 15.7 Cu. Ft.
Vol. / 3 Cu. Ft./Min. (rate), = 5.23 Min

As you know gas in compressible fluid. You should clear what is the pressure of filling gas. I mean 3 ft/ min i.e 3 CFM at what press. condition ? Ifi it is atm, time will be more. if it is say 1 kg/cm2g ..time will be less. hence depends upon the filling gas pressue. And againWhat tank press you r looking for ? If tank is vaccum, just .0000000000000001 % of GAS WILL FILL UP THE TANK BUT PRESSURE WILL BE ABS VACUUM .

Volume = (1^2) * Pi * 5 = 15.71 ft^3
Fill Time = Volume/Rate = 15.71 Ft^3 / 3 ft^3/min = 5.24 min
