Explain how the concept of thermal resistance can be used in the analysis of heat transfer problems
2. The attempt at a solution
So I'm made a few key points but I am not sure if I have answered the question fully:
- Thermal resistance is a heat property and a measurement of a temperature difference by which an object or material resists heat flow
- (Conduction) The heat flow can be modelled by analogy to an electrical circuit where heat flow is represented by current, temperatures are represented by voltages, heat sources are represented by constant current sources, absolute thermal resistances are represented by resistances and thermal capacitors are represented by capacitors.
- Thermal resistance R has the units (m^2*K)/W
