Chapter , Problem 7.108(choose chapter or problem)
The use of rock pile thermal energy storage systems has been considered for solar energy and industrial process heat applications. A particular system involves a cylindrical container, 2 m long by 1 m in diameter, in which nearly spherical rocks of 0.03-m diameter are packed. The bed has a void space of 0.42, and the density and specific heat of the rock are 2300 kg/m3 and cp 879 J/kg K, respectively. Consider conditions for which atmospheric air is supplied to the rock pile at a steady flow rate of 1 kg/s and a temperature of 90 C. The air flows in the axial direction through the container. If the rock is at a temperature of 25 C, what is the total rate of heat transfer from the air to the rock pile?
