Best Answer: the rate of diffusion is directly proportional to the concentration gradient. The greater the difference in concentration between two areas, the greater the rate of diffusion.
EPC-40: Electrical Plastic Conduit : Designed for normal duty application. EPC-80: Electrical Plastic Conduit : Designed for heavy duty application.
Conduits: Electrical Metallic Tubing (EMT). Another example of rigid electrical conduit is the EMT, also known as Electrical Metallic Tubing. An EMT conduit is made of steel; in some cases aluminum is also used, cheaper than a galvanized rigid conduit and lighter than a GR conduit.onduits: Aluminum Conduits. An aluminum conduit is a rigid conduit commonly used in commercial and industrial applications. Aluminum conduits are used to prevent corrosion and are the preferred conduit used in areas where large amounts of water and corrosion-prone areas.
