WebMay 19, 2011 · For instance, if you pick a circular cross seciton, with D = 2r = 20 cm (about 8 inches), then A = 315 cm^2. If you have 1.5 cm of liquid between the two plates, then A/L = 210. If your meter reads 100K Ohms, then you know the resistivity is 210 x 100K = 21M Ohms. By the way, the conductivity I found for "ultra-pure" water is 18.2M (Ohm x cm). WebSep 24, 2024 · 2003. Q. I work in a small laboratory. Our DI water supply is kept in our lab in a 5 gallon container. Our initial requirement was to maintain at a minimum resistivity of 50,000 ohm-cm. We are now instructed to maintain at a …
