A composite rod is made from
stainless steel and iron and has a length of 0.535 m. The cross
section of this composite rod is shown in the drawing below and
consists of a square within a circle.The square cross section of
the steel is 1.27 cm on a side. The temperature at one end of the
rod is 80.6 °C, while it is 19.3 °C at the other end. Assuming that
no heat exits through the cylindrical outer surface, find the total
amount of heat conducted through the rod in four minutes.

A) A stainless steel bar 11.8 cm long is welded end to end to a copper bar 22.6 cm long. Each bar has a square cross section, 2.0 cm on a side. The free end of the stainless steel bar is kept at 100∘C by placing it in contact with steam, and the free end of the copper bar is kept at with 0∘C by placing it in contact with ice. Both bars are perfectly insulated on their sides. What...
Composite system is made of steel rod \(A D\), aluminium rod \(C F\) and copper rod \(B E\) which have square cross section with edge lengths of a \(_{\text {sT }}\) a \(a_{A}\) and a \(\mathrm{Cu}\) respectively. Copper rod \(\mathrm{BE}\) and aluminium rod \(\mathrm{CF}\) is perfectly bonded to steel rod \(\mathrm{AD}\) at points \(\mathrm{B}\) and \(\mathrm{C}\). If the system is built when the temperature is \(\mathrm{T}_{0}\) what \(1 / C^{\circ}, a_{C u}=1710^{6} 1 / C^{\circ}, a_{s t}=199 \mathrm{~mm}, a_{N}=96.2 \mathrm{~mm},...
A tube with length of 1 m is made from steel (k 15 W/m/K) having a square cross section with a circular hole through the center, as shown below Calculate the steady state temperature distribution across the cross section and the total rate of heat transfer if the inner surface is held at 20 °C, and the outer surface is held at 100 °C. How does the heat rate vary with grid resolution? Consider 9 and 17 grid points across...
Two metal rods of equal length-one aluminum, the other stainless steel-are connected in parallel with a temperature of 22.0 ∘ C at one end and 130 ∘ C at the other end. Both rods have a circular cross section with a diameter of 2.50 cm. Part A : Determine the length the rods must have if the combined rate of heat flow through them is to be 30.0 J per second.Please express answer in meters. Part B: If the length...

A copper rod has a length of 2.0 m and a cross-sectional area of 3.4 x 10-4 m2. One end of the rod is in contact with boiling water and the other with a mixture of ice and water. What is the mass of ice per second that melts? Assume that no heat is lost through the side surface of the rod. m/t = i
One end of a long rod 3 cm in diameter is inserted into a furnace with the (3 outer end projecting into the outside air. Once the steady state is reached the temperature of the rod is measured at two points, 15 cm apart and found to be 140°C and 100°C, when the atmospheric air is at 30°C with convection coefficient of 20 W/m2.K. Calculate the thermal conductivity of *.the rod material Consider a stainless steel spoon(k = 15.1 W/m.K), partially...
Heat Transfer
Problems 1. A window pane (1/8 inch thick) in an old house owned by a professor is 3 ft. by 4 ft. He likes to be warm in the winter so the inside temperature is kept at 70 °F even when the outside temperature is 10 •F. For this problem assume the inside and outside temperatures are for the window surface. How much heat is transferred through the window (k=.54 BTU/hr ft ° F)? 2. A small heated...
