Heat Transfer: Convection and Newton's Law

This lecture covers the phenomenon of heat transfer by convection, where heat is transferred through the macroscopic movement of fluids or gases. The instructor explains the empirical law governing heat convection, known as Newton's law, and provides a physical interpretation of this law. The lecture also delves into the factors influencing the heat transfer coefficient, such as fluid properties, object geometry, and phase transitions. By examining examples of different substances and the impact of fluid velocity on heat transfer efficiency, the lecture illustrates how convection can be highly effective in certain conditions.
