Heat Transfer Problem 1
Calculate the heat transfer rate per metre length when a steel pipe conveying steam is insulated. The pipe has an inside diameter of 20 cm, and outside diameter 30 cm. The lagging is 10 cm thick and has a thermal conductivity ki of 0.1 W/m K. The thermal conductivity of the pipe wall kp is 80 W/m K, the steam is at 300oC and ambient surrounding air is at 20 oC. You may assume the pipe is sufficiently long with hin = 40 W/m2 K, and hout = 16 W/m2 K

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?
