Hi,
I'm using danfoss coolselector 2 software for selection of liquid and wet return line of ammonia refrigeration system. It provides 3 selection criteria for that which are as below:

Pressure Drop or Velocity
Pipe Size
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?
