WebThe overall energy balance of the solid is given as: (4) where ρ is the density of the solid (kg·m −3 ), V is the volume (m 3 ), Cp is the heat capacity (J·g −1 ·K −1 ), T is the temperature of the solid and T∞ is the ambient air temperature. The term ρ Vcp is called the lumped thermal capacitance of the solid. Webcylindrical geometry, a number of guess temperature profiles have been assumed to obtain a generalized solution. Based on the analysis, a modified Biot number has been proposed that predicts the temperature variation irrespective the geometry of the problem. In all the cases, a closed form solution is obtained between temperature, Biot number, dawkins bills football
