.0124 W/cm-K. It has the shape of a rectangular bar with cross sectional area of 1 cm2and length of 3 cm. One end is maintained at 300 °C and the other end at 100 °C. The bar carries a current of 50 A and has resistivity of 1.5x10-3ohm-cm. Assuming the longitudinal surface is insulated, calculated the midpoint temperature in the ba

In a glass plant in Cavite, a furnace has fire-brick walls made up of the following two materials in series :                        Non-corrosive brick as inner layer (material 1) Clay brick as outer layer (material 2) Thickness 4.5 inches 8 inches Thermal conductivity k1 k2   The temperature inside the furnace (inside wall surface of the non-corrosive brick) is found to be 1105 oF while the outside temperature (outside wall surface of clay brick) is 365 oF.   This is not the desired temperature inside the furnace so engineers thought of lagging the furnace walls with another material to reduce heat loss.  The additional lagging material consists of magnesia layer which is 2 inches thick and has a thermal conductivity of 0.04 Btu /h.ft.oF.   During a test run on the furnace with the magnesia lagging material now,  new temperature readings were recorded : Point of measurement Temperature reading Inside furnace (inside wall surface of non-corrosive brick      1355 oF Interface between…

Solve this one correctly. Very very important for me.

Determine the thermal conductivity of water vapor at 174°C.

In the figure below, it is known that the thermal conductivity of k1 = 0.06 W/mK, k3 = 0.04 W/mK, and k4 = 0.12 W/mK. The thickness of the layers is L1 = 1.50 cm, L3 = 2.8 cm, and L4 = 3.50 cm. Known temperatures T1 = 30°C, T12 = 25°C, and T4 = -10°C. Energy transfer through walls is constant. How much is T34?

A heating element made of tungsten wire connected to a large battery that has negligible internal resistance. When the heating element reaches 80.0°C, it consumes electrical energy at a rate of 480 W. Assume that the temperature coefficient of resistivity has the value given in Table 25.2 in the textbook and that it is constant over the temperature range in this problem. In the equation R(T) = Ro [1 + a(T - To)] take To to be 20.0°C. Part A What is its power consumption when the temperature of the heating element is 110.0°C?
