what type of highly flexible wire conducts the most electricity?
the wire must be really durable and very easy to bend, almost like bending a piece of cloth or string (or as close as possible) maybe a wire?

I am on a building committee, and need to know how many kids per square foot I can have comfortably fit in a (square or rectangular) church Sunday School classroom with tables. I know there is an occupancy load provided by the local fire Marshall, but I don't want an overcrowded room.
Thanks!!!

In a compressor application where operation is oil free, but the shaft must be well sealed against leaks and construction costs must be kept to a minimum, a mechanical shaft seal fits all design specifications but I anticipate a lack of lubrication may present problems leading to premature wear and failure.
Typically, the sealing surfaces may be polished carbon against creamic. Other material options are available.
Pressure drop across the seal when operating should not exceed (for my application) 35 PSID. When off, the pressure differential may be as high as 135 PSID. In some cases the compressor may operate with a negative internal pressure that should not exceed 0.5 atmospheres.
Due to a wide variety of chemicals in the gases, reasonably inert materials that can tolerate a wide variety of temperature ranges are best but the main issue here is: Can the sealing surfaces survive without any lubricant.
Comments and insights please!
Any recommendations?
