Design Considerations

• Tower diameter 0.5 3 m
• Height 1-15 m
• Qa/Qw 5- several hundreds
• Controlled by flooding and pressure drop
• Flooding air goes up too fast blocks downward
  movement of water
• Channeling Water flows down wall rather than
  packing materials
• Pressure drop 200 400 N/m2- per meter of tower
  height
