    This is the closest I could find:


    For dry air at sea level and 72 deg. F, the true specific volume = 13.399 cu. feet per pound 

    Therefore the weight of dry air = 1/13.399 = 0.0746 pounds per cu. ft. 

    The mixture of dry air and saturated steam at sea level and at 72 deg F. = 13.76 cu. feet per pound 

    Therefore the weight of saturated air = 1/13.76 = 0.0727 pounds per cu. ft.
