A spherical tank made up of stainless steel is to be used for storage of oil at 150°Cthat is needed for heating purposes in a plant. It is decided to insulate the tank in order todecrease the heat loss to the surroundings, which is at 20°C having heat transfer coefficient of 25W/m2.K. The heat loss is compensated by the heating resistance inside of the tank. There are twotypes of insulating material present at this plant each is enough for covering the tank with onlyone layer. These are;Type 1: k=0.1 W/m.K thickness=5cmType 2: k=0.25 W/m.K thickness=5cmAn engineer is thinking about the most efficient way of covering the tank in order to minimize theheat loss. Please help him for this purpose. Is it more efficient to cover type 2 over type 1 or type1 over type 2? Explain why?

The thermal conductivity of a solid material can be determined using asetup similar to the one shown in the accompanying figure. The thermocouples are placed at 2.5 cm intervals in the known material (copper alloy, k - 52 w/m.k) and the unknown sample, as shown. The known material is heated on the top by a heating element, and the bottom surface of the sample is cooled by running water through the heat sink shown. Determine the thermal conductivity of the unknown sample for the set of data given in the accompanying table. Assume no heat loss to the surroundings and perfect thermal contact at the common interface of the sample and the copper.
