In an experiment to determine the thermal conductivity of a new metal alloy, a bar of the metal is completely surrounded by insulation and exposed to 707 W of constant heat energy at one end. The bar has a radius of 0.074 m and a length of 0.331 m. The entire set-up is place in a cold room and once the system has reached steady state conditions, the temperature at the hot end is measured to be 63.8°C and the temperature at the cold end is measured to be 14.9°C.

Another metal alloy was tested using the same set-up (same size and heat input) as question above. If the temperature difference between the hot end and the cold end for this test was found to be 30°C, it would indicate that this material is a better conductor of heat than the material tested in question above.

An engineer is designing a wire using an unknown material that will carry large amounts of electricity. The resistive heating of a 50.28 g wire is expected to add 560 J of heat energy during a 17-minute operating cycle. What is the temperature increase of the wire? You may use the following information about the unknown material to answer the question: Specific Heat = 0.313 J g-1 °C-1 Density = 7.98 g/cm3 Coefficient Thermal Expansion = 6.7 µm m-1 K-1
A house has an electric heating system that consists of a 300-W fan and an electric resistance heating element placed in a duct. Air flows steadily through the duct at a rate of 0.6 kg/s and experiences a temperature rise of 7°C. The rate of heat loss from the air in the duct is estimated to be 300 W. Determine the power rating of the electric resistance heating element.
You are insulating a metal pipe carrying a hot fluid. The outside Diameter of the pipe is 3.5 cm, and the pipe has a length of 7.7 meters. Due to the fluid inside the pipe, the outside surface of the metal fluid pipe is kept at a constant temperature of 85.0°C. The metal pipe is inserted inside of a thin-wall circular tube, which has an inside diameter of 11.2 cm (ignore the resistance of the thin-wall circular tube). The space between the outside of the hot metal pipe and the inside of the thin-wall circular tube is filled with foam insulation, k = 0.036 W/m-K. The outside of the thin-walled circular tube is kept at a constant temperature of 28.0°C. Due to a manufacturing error, the metal pipe was not centered inside the thin-wall tube when the foam insulation was added, but was instead installed with an eccentricity of 2.0 cm (i.e. the center of the metal pipe is 2.0 cm distance from the center of the thin-walled circular tube). Calculate the increase in the heat transfer rate due to…
