Can someone tell me the conductivity of dry un-ionized air. I have assumed it to be zero, but I realize I probably am wrong.
How does one express the conductivity of fluid? ohms per what? do you have a good link on this subject?

The problem with air is that once the potential gets high enough ionization occurs. About 10,000 volts per inch
"Although air is normally an excellent insulator, when stressed by a sufficiently high voltage (an electric field strength of about 30 kV/cm [1]), air can begin to break down, becoming partially conductive."

Conductivity of fluids is usually ohms per meter.

yes you are wrong it is not zero but very close to it. as to fluid conductivity,,, it depends on the fluid since each type of fluid has different characteristics and will conduct heat, electricity etc at a varying rate
