A horizontal pipe having a surface temperature of 67 °C and diameter of 25 cm is buried at a depth of 1.2 m in the earth at a location where k = 1.8 W/m-°C. The earth surface temperature is 15 °C. Calculate the shape factor if the pipe length is 10 m.
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. Use h=30 W/m²K, estimate the surface temperature of the elephant. Do you…

A gas flows over a heated horizontal surface with a surface temperature that is uniform and higher in value than the temperature of the gas. The local convective coefficient in W/m².K of this flow with convective heat transfer can be given as a function of the distance x (in meters) from the beginning of the horizontal surface by: h = A xD + B x + C, where A = -2.4, B = 14.8, C = 9.3 and D = 2.7. Based on this information, calculate the average Nusselt number of the flow over the plate if it is three meters long. Consider: ρgas = 0.9950 kg/m³; kgas = 30 x 10-3 W/m.K. Note: Use the equations given in the book by Schmidt et al. for problem resolution.
