5. A flaked cereal is of thickness 2L=1.2 mm (or the characteristic length Lc = V/A= 0.6 mm). The density, specific heat, and thermal conductivity of the flake are p 700 kg/m3,cp = 2400J/kg K, and k = 0.34 W/m K, respectively. The product is to be baked by increasing its temperature from Ti = 20 °C to Tr = 220 °C in a convection oven, through which the product is carried on a conveyor. If the oven is Lo...

A plane wall of thickness 2L= 30 mm and thermal conductivity k= 3 W/m·K experiences uniform volumetric heat generation at a rate q˙, while convection heat transfer occurs at both of its surfaces (x=-L, +L), each of which is exposed to a fluid of temperature ∞T∞= 20°C. Under steady-state conditions, the temperature distribution in the wall is of the form T(x)=a+bx+cx2 where a= 82.0°C, b= -210°C/m, c= -2 × 104°C/m2, and x is in meters. The origin of the x-coordinate...

NE Steel tubes (k =35 W/m2.K) of 400-mm inner diameter and 30-mm wall thickness are used to route superheated steam from the boller to the turbine in a power plant. Safety and economic concerns make it practical to add a 200-mm layer of Insulation (k =0.1 W/mK) to each tube, which is wrapped in a thin sheet of aluminum with an emissivity e =0.15. The air (with a convective coefficient h =5 W/m2K) and wail temperatures of the plant are...
