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.
Three basic types of steel conduit are in use today: rigid metal conduit, intermediate metal conduit, and electrical metallic tubing. Let's take a closer look at the features of each type. Rigid metal conduit â RMC (ferrous metal) .RMC is a listed threaded metal raceway of circular cross section with a coupling, which can be either a standard straight tapped conduit coupling or the integral type (Photo 1).et's take a closer look at the features of each type.
