Thermal Resistance • Opposition to the flow of heat. • dependant on the thermal conductivity of a material. • High thermal conductivity yields low thermal resistance
Thermal Resistance Pressure drop (P) Rfluid = Volume flow rate (Qv)
Thermal Resistance -k A T Qv= x -T x Rthermal = = Qv k A
Resistance in Series • Same as electrical resistance in series. • Total resistance is sum of individual resistances • P.221
