    Condensation and Freezing in a Duct

    Thanks a lot for your attention. But, what about the freezing possibility of this condensated water inside the duct? Does this condensated water turn to ice easily with air flow 30000 m3/h, velocity 4 m/s, and mixed air temperature inside the duct approximately -14 / -15 C?

    Condensation and Freezing in a Duct

    I have a simple question that I couldn't figure out. We have L=60 m, with dia 1600 mm Stainless Steel (thickness=1,6 mm)round duct at outside. Outside minimum temperature is -36 C, with RH = 90%. The two ends of duct are open. From right end, 23500 m3/h air enters at -36 C. At the center of the...

    air leakage velocity calculation

    IRStuff, Please find the excat text; For the sizing of the compressed air bottle banks the airflow should be determined as follows: For the air flow from the outside door when open, a face velocity of 0.3 m/s for the duration of 5 seconds shall be taken. Also to allow one person per entry...

    air leakage velocity calculation

    Regarding that question, let me explain the real case; With my colleague saliba11, we are trying to design an airlock with dimensions 2,5*3*3(h) m for Refuge buildings. This room under +50 Pa according to the outside (1 atm) in normal case, which is pressurized by HVAC system.In case of any...
