(1) A steel plate with a thickness of 5cm and an initial temperature of 250 °C was suddenly placed in an air environment with a temperature of 20 °C. The heat transfer coefficient of convection between the wall of the steel plate and the air was h=100 W/(m²K), and the thermal conductivity of the steel plate was known to be λ=47 W/(mK) and the thermal diffusivity a = 1.47 x 10³ m²/s. Please calculate the temperature of the steel plate after 5 minutes.
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…

African elephants have a large body with a surface area of the trunk as A= 11 m². Typically, elephants roll into wet mud in summer time. The evaporation of moisture from skin surface enhances the convection heat transfer rate to h= 30 W/m²K (without evaporation the h value is very small ~ h=8 W/m²K). The normal metabolism of elephants (the total heat generation rate in the elephant body) is Qgen = 2500 W. Based on what you learned in ENME321, the surface temperature of the elephant (or any object with heat generate rate) is calculated using the following equation: Ts = Too+ Qgen /(h A). The air temperature Too is 32°C. Elephants are not considered as being overheated if the surface temperatures are lower than 37°C. a. The elephant has not rolled into wet mud. Use h=8 W/m²K, estimate the surface temperature of the elephant. Do you think that the elephant will be overheated? b. The elephant has rolled into wet mud.
