Surface Tension and Water Contamination as Related to the Selection of Flow System Components1
- G. C. Topp2
The changes in air-water interfacial tensions caused by contaminants leached from 16 different materials were measured. This was an attempt to find noncontaminating components for a water flow system. A modification of the Wilhelmy slide method using a small volume of water was adopted to measure surface tensions. Only seven of the materials tested showed no measureable effect on the surface tension of the water. In addition to a reduced surface tension caused by the nine remaining materials there was an increased contact angle.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
