The rate of heat transfer through a composite pipe is given by the equation: Cold fluid (air) hot B (A) Hot fluid i 2tL(tnf – tef) Q = 1 + In (r2/ri) , In (r3/r2) . 1 + + ka kg hef.3] Where the subscript hf refers to the hot fluid and cf refers to the cold fluid. h is the convective heat transfer coefficient and k is the thermal conductivity. Write the equation in primary dimensions and show that it is homogenous.
