    7557120 kg/hour

    Explanation:

    Given data;

    Volume of air in one second = 1640 L

    Density of air = 1.28 kg/L

    Mass of air in 1 hour = ?

    Since mass = density * volume

    ==> Mass of air in one second = 1.28 * 1640 = 2099.2 kg

    ==> Mass of air in one minute = 2099.2*60=125952 kg

    ==> Mass of air in one hour = 125952 * 60 = 7557120 kg

    So rate of flow of air is 7557120 kg/hour
