Transcribed Image Text:A 60 cm-long, 3 cm-diameter AISI 1010 steel rod is welded to a furnace wall and passes
through 20 cm of insulation before emerging into the surrounding air. The faurnace wall is at
3000C and the air temperature is 200C. Estimate the temperature of the bar tip if the heat
transfer coefficient between the rod and air is taken to be 13 W/m2 K.

- A plane wall has a thermal conductivity of 20 W/(m-K) and generates heat at 0.5 MW/m3. The wall is 0.2 meters thick and is perfectly insulated on one side. The other side is exposed to fluid at 100 °C. The convective heat transfer coefficient between the wall and the fluid is 400 W/(m2 K). Determine the maximum temperature in the wall.arrow_forwardThe exhaust duct from a heater has an inside diameter of 114.3 mm with ceramic walls 6.4 mm thick. The average k=1.52 W/m· K. Outside this wall, an insulation or rock wool 102 mm thick is installed. The thermal conductivity of the rock wool is k= 0.046+ 1.56 x 104 T°C (W/m · K). The inside surface * = temperature of the ceramic is T1 = 588.7 K, and the outside surface temperature of the insulation is 311 K. Calculate the heat loss for 1.5 m of duct and the interface temperature T2 between the ceramic and the insulation. [Hint: The correct value of km for the insulation is that evaluated at the mean temperature of (T2 + T3)/2. Hence, for the first trial assume a mean temperature of, say, 448 K. Then calculate the heat loss and T2 Using this new T2, calculate a new mean temperature and proceed as before.]arrow_forwardExample • The cylinder is made from aluminum with diameter and thickness of 5 cm and 1 cm respectively.
