A typical scuba tank when fully charged, contains 12L of air at 204 ATM. Assume an empty tank contains air at 34 ATM and is connected to an air compressor at sea level. The air compressor intakes the air from the atmosphere, compress it into high pressure and then In put the high pressure air into the scuba tank. If the average flow rate of air from atmosphere into the intake port of the air compressor is 290 L/min, how long will it take to fully charge the scuba tank? Assume the tank remains at the same temperature as the surrounding air during the filling process.
