A Note on the Conductivity of Electrolytes for Analog Models
During the measurement of piezometer shape factors with an electrolytic tank, it was found that the electrolyte resistance was temperature-dependent to an appreciable extent. A study of temperature effects showed that the conductivity of ordinary tap water varied by only 1.9% per °C, compared to almost twice as much for copper sulfate solutions. It was concluded that tap water was the more suitable electrolyte where extremely accurate measurements are to be made in an electric analog model.
