Thermal Resistance: Materials and Insulation
This lecture covers the concept of thermal resistance in materials with different conductivities and thicknesses, focusing on heat flow through insulating layers. It explains how to calculate overall thermal resistance, considering external surfaces and interfaces. The lecture also discusses the use of double and triple glazing systems to reduce heat losses, emphasizing the importance of thermal conductivity and thickness ratios. Additionally, it explores the process of Newtonian cooling for quenching steel parts, analyzing cooling rates and exponential temperature decreases.
