Flue gas volume: 10,000 Nm3/h (standard cubic meters), humidity: 7.7%. What is the amount of water content in tons?

The concept of humidity is related to temperature (assuming that the pressure of the flue gas is roughly at atmospheric pressure, so this can be ignored); without temperature, it’s not possible to determine the saturated pressure of the steam. Only by knowing the saturated pressure and the humidity level can one determine the amount of moisture present. Assuming this is not humidity but rather the content of water vapor: the flue gas volume is 10,000 Nm3/h, with 7.7% water vapor content, which is typically given as a volume percentage. Multiplying these values gives 770 Nm3/h of water vapor. Dividing this by the molar volume of 22.4, and then multiplying by the molecular weight of 18, results in 619 kg/h.
