Calculate the overall heat loss and the temperature profile for each interface if the length of the cylinder is 50 m.Please write your answers legibly.
(Heat Transfer) A furnace wall is composed of 20.32cm of fireclay brick (k=1.32 W/m^2.k), 10.16cm mineral wool (k=0.039 W/m^2.k), and 10.16cm of common brick (k=0.69 W/m^2.k). The surface temperature of the common brick is 60°C and the interface temperature between the common brick and the mineral wool is 30°C. The temperature of the gases is 1000°C and the temperature of the outside air is 30°C. Determine the outside air coefficient hc=W/m^2.k
The hot combustion gases of a furnace are separated from the ambient air and its surroundings, which are at 25°C, by a brick wall 0.15 m thick (Figure la). The brick has a thermal conductivity of 1.2 W/m·K and a surface emissivity of 0.8. Under steady-state conditions an outer surface temperature of 100°C is measured. Free convection heat transfer to the air adjoining the surface is characterized by a convection coefficient of h = 20 W/m².K. What is the brick inner surface Q1 a) temperature?
= A long rod of 60-mm diameter and thermophysical properties p 8000 kg/m³, c C = 500 J/kg-K, and k = 50 W/m-K is initially at a uniform temperature and is heated in a forced convection furnace maintained at 750 K. The convection coefficient is estimated to be 1000 W/m².K. What is the centerline temperature of the rod when the surface temperature is 570 K? The centerline temperature of the rod is i K.
To reduce heat flux, the skin is wrapped with a clothing material. What should be the thickness of the clothing material covering the surface of this skin tissue to reduce the heat flux to half of its original value? What is the temperature at the skin-clothing material interface? Note: if you think you need to have more information to solve this problem, you're free to make assumptions. Please state them clearly in your answer, if you need to make such assumptions.
A 10 cm-thick beef steak is being frozen in a -40°C room. The product has 73% moisture content, density of 970 kg/m³, and thermal conductivity (frozen) of 1.1 W/(m K). Estimate the freezing time using Plank’s equation. The product has an initial freezing temperature of -1.75°C, and the movement of air in the freezing room provides a convective heat-transfer coefficient of 10 W/(m² K). a. tf =... h
