Freight Surcharges. BAF refers to floating part of sea freight charges which represents additions due to oil prices. Usually BAF charges are determined by Carrier Conferences to be applicable for a certain period on a certain trade route. These Carrier Conferences are seen as a cartel for fixing prices.
Heat transfer. Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy (heat) between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes.
This is called heat transfer. (Remember, we learned that energy transfer is when energy moves from one thing or place to. another, but the energy type stays the same). Heat can transfer (or move) in 3 ways: conduction, convection, and radiation. As you read about the three types of heat transfer, pay attention to:
