The cylinder has a high thermal conductivity and the inner tem- perature T at point r outside the cylinder is fixed. An example is the case where the cylinder is a metal pipe with saturated steam inside. The outer surface of the insulation at T, is exposed to an environment at To where convective heat transfer occurs. It is not obvious if adding more insulation with a thermal conductivity of k will decrease the heat-transfer rate. At steady state, the heat-transfer rate q through the cylinder and the insulation equals the rate of convection from the…

Please continue my work I've included in the image. show that equation (1) leads to equation (2) by replacing the L.H.S and R.H.S with the equations shown in the image. (this is what I've done so far)

I need solutions to this question
