A steel sphere (AISI 1010), 100 mm in diameter, is coated with a dielectric material layer of thickness 1.75 mm and thermal conductivity 0.04 W/m.K. The coated sphere is initially at a uniform temperature of 500°C and is suddenly quenched in a large oil bath for which T = 100°C and h = 3000 W/m².K. Estimate the time, in h, required for the coated sphere temperature to reach 150°C. Hint: Neglect the effect of energy storage in the dielectric material, since its thermal capacitance (pc)is small compared to that of the steel sphere. t = h

Assume that the head can be modeled as a hemisphere (radius ro 90 mm) with a single layer of brain tissue (k-0.5 W/m °C). The bottom of the hemisphere is insulated. The head surface is assumed exposed to a convection environment (h-8 W/m²K, T-25°C). Based on the boundary conditions, the brain tissue temperature can be treated as 1-D, i.e., T.(r), where r is the radial variable in the spherical coordinates. The volumetric metabolic heat generation rate in the brain is uniformly distributed and is equal to q=10000 W/m³. Consider two situations, a) no blood perfusion is considered; b) blood perfusion rate is uniform in the brain and is equal to @=0.01 s¹. The governing equation (steady state, 1-D heat transfer in the spherical coordinate system, with or without the Pennes perfusion term) and boundary conditions for both situations can be written as: k₁ 1 d 2 r=0 dr dT, dr dT, 17/17) + 0 dr =0 T,(r)= dT, r=r-k₁- =h(T, -T.) dr (a) For the first situation without considering blood perfusion…

In the arctic sea, the ice sheets are melting. Let's calculate the temperautre distribution in one such ice sheet. The sheet is 2 m thick. Under the sheet there is ice-water mixture and it can be assumed that the temperature of the bottom surface of the ice sheet is approximately 0°C. Air at -20°C is blowing above the sheet. The convection coefficient of air is 15 W/m².K. The thermal conductivity of ice is 2.2 W/m.K. What is the temperautre of icesheet at its center (i.e., at 1 m from the surface)?
