Liquid transport/wick system help needed

  1. Feb 24, 2012 #1

    I'd like to know how to calculate the transport of a certain volume of water in a vertical wick system.

    Said system is as follows:

    one end of a rope, hanging vertically 5 meters, stands in a bucket of water. The other hand is embedded in a sponge located 5 meter above the bucket.

    Assuming that water evaporates from the sponge over time (thus making overwetting not an issue), I'd like to know which rope diameter/material would be needed to transport, say, 0.03 liters/hour up in the sponge.

    Also I'd like to know what are the height limits for said system and if a hollow plastic tube would be more efficient at trasporting water by capillary action.

    I include a very simple drawing, if I had better IT skills and hardware I'd have uploaded one drawn by hand.

    Thank you very much :)
