The above problem is based on the formula of rate of heat transfer.The rate of heat transfer depends on the following parameters- conductivity,area of cross-section,change in temperature,length.The solution is given below:
a) Rate of heat transfero KAST w whene K= conductivity A = area of cross-section AT= temperature change e= length .: Rate of
