    Answer:

    Flow rate of air is given as 83.33 cubic feet per minute

    Explanation:

    As we know that total volume of the air flow is given as

    V = 10,000 cubic feet

    also we know that total time is

    t = 2 hours = 120 min

    now we have flow rate given as

    Q = \frac{V}{t}

    Q = \frac{10000}{120}

    Q = 83.3 cf/m
