Heat Transfer The variation of thermal conductivity of a metal with temperature is often correlated using an expression of the form K = K₀ + at. where, K is the thermal conductivity and T is the temperature (in °K). The units of 'a' in SI system will be None, A is just a number W/m W/m.k² W/m.k None, A is just a number W/m W/m.k² W/m.k ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer Double pipe heat exchangers are used because it occupies less floor area because it is less costly when heat transfer area required is very high when heat transfer area required is very low because it occupies less floor area because it is less costly when heat transfer area required is very high when heat transfer area required is very low ANSWER DOWNLOAD EXAMIANS APP
