1. A copper pipe (K = 50.0 W/m.K) having a 0.075m O.D is covered with a layer of magnesia (K = 0.07W/mK) having 0.125m outside diameter which in turn covered with a 0.15m outside diameter layer of fiberglass insulation (K = 0.048 W/m.K). The copper pipe wall outside temperature is 400 K and the outer surface temperature of the fiberglass is 275K. a) Calculate the steady state heat transfer along the composite pipe, b) Also, determine the copper pipe wall thickness for a temperature drop of 10K between the copper pipe. Lastly c) What is the total resistance? Tolia the value of
