10-m-long copper tube with a diameter of 25 mm is used for transporting cold fluid. The cold fluid flow inside the tube causes the tube surface temperature at 3°C to be colder than the ambient temperature. As a result, moist air condenses at 27°C on the tube outer surface. The tube is situated in the vicinity of high voltage devices, and water from the condensation can cause electrical hazard. It has been determined that both film condensation and dropwise condensation can occur on the tube surface. To prevent electrical hazard, a system is to be implemented to remove the condensate and prevent it from coming in contact with the high voltage devices. Size the system so that it is capable of handling the condensation rate from the tube surface.
