- To test the absorbency of different types of wicking materials.
- 1 Wooden bar of 2" x 4" x 84"
- 1 Wooden rod of 48" x 1/4"
- 3 Basins 11 1/4" x 9 3/8" x 1 1/2"
- 3 Binder clips of 1/2"
- 4500 ml of water (1)
- Testing Subjects: Wick Materials
- Pure wool
- Pure cotton
- Cut the wooden bar into two bars of 36" and two 6" of length
- With the use of a drill, drill bit and screws, attach each 36"-long bar to one of the 6" long bar, so that there smaller bars provide support and thus the long bar can stand. (See Figure 1)
- Make a hole in each bar near the edge, opposite to the 6" bar attachment. The hole should be roughly bigger than 1/4", big enough for the rod to slide through the holes. Make sure the holes are at the same level, to keep to rod horizontal.
- Stand 36"-long bars, separated by roughly 40".
- Insert rod through holes.
- Fill basins with 1500 ml of the contaminated water sample
- Set basins on the floor, underneath rod.
- Hang wick materials on rod. Make sure the materials sit on the bottom of the respective basins
- Running the experiment
- Record the experiment starting time: right after all the wicking materials are sitting on basing
- Measure the average height reached by the water in each wick material.
- Repeat step 2 every hours, until a total of 4 samples are collected.
- Record data.
- After all four samples are collected remove materials from basins and weight water in each basin to find the amount of water absorbed per material.
The following are the results in terms of the vertical wicking and the water absorbed by the material.
The following picture shows the vertical wicking of the samples. The samples are, starting from left pure wool, pure cotton and felt respectively
- Pure wool is more absorbent than the other materials.
- Even though the height of felt is approximately 50% higher, the absorption of the material (Total Volume of Water Absorbed) has a more significant impact on water evaporation than the height water has reached on the material. Also, water will be fed from the top of the device, decreasing the gravity effect on water.
