travels through some medium which in general offers resistance to the heat flow.Both these factors,the temperature difference and the resistance to heat flow,affect the rate of heat transfer.As with other rate processes,these factors are connected by the general equation plastic materials have thermal conductivities as low as 0.026 Jm CHAPTER 5 HEAT TRANSFER THEORY - NZIFST - HomeIn the case of heat conduction,the equation,rate = driving force/resistance,can be applied directly.The driving force is the temperature difference per unit length of heat-transfer path,also known as the temperature gradient.Instead of resistance to heat flow,its reciprocal called the conductance is used.Alfa Laval - Compact heat exchangersThe overall flow of the two media is counter-current in a compact heat exchanger,i.e.the hot medium exits where the cold medium enters.This means the cold medium can be heated to a temperature very close to that of the entering hot medium.The temperature difference,T,can be as low as 2 low temperature resistance medium plate lsaw#176;C (3.6 low temperature resistance medium plate lsaw#176;F).
