23 ft^3 of air was drawn from a ventilation duct and measured by means of a dry gas meter. the meter's temperature averaged 60 F and the meter gage pressure was -1.9" H2O. Barometric pressure during the sampling was 752 mm Hg. Calculate the volume in standard cubic feet and in standard cubic meter (25C, atm)
