    Ammonia Wet Return Line



    Hello,
    Please let me know what is the selection criteria of wet return line of ammonia?
    and what will be the suitable line size for ammonia wet return line if the cooling capacity is 287 kW and circulation ratio is 4?

    Large is the short answer.

    sorry a little politeness goes a long way, and a lot more information required.

    1. Pressure Drop or Velocity
    2. Pipe Size
    3. Saturated Temp. Drop (0.02K/m)

    Please guide me which one is most accurate one and what is the default value of pressure drop in this software? and what are the recommended velocities for both lines?

    to get a good suggestion you must give us as much as possible data regarding your question ... i.e. evaporation pressure/temp, condensing pressure/temp, distance from evaporator to suction separator ...
