How to determine the water volume?
Thread Content
Given the moisture content d (g/kg) of moist air, and the heat absorbed by moist air q (in kJ/kg), I want to use the latent heat of vaporization of water, which is 2501 (in kJ/kg). How can I determine the amount of water I need to add using these known conditions? The teacher said to use q/2501, but that way the units are canceled out. I can’t figure it out for now; please advise me. My email: 154331983@163.com
I’m not exactly sure about the details, but what your teacher said isn’t correct either. The heat absorbed by air includes sensible heat and latent heat, and you’re only taking into account the latent heat at the moment; in my opinion, that’s not quite right. I need to look up some information and read books – I haven’t read anything in a long time, so I’ve forgotten everything
