Aplane wall of thickness 0.163 m experiences uniform volumetric heating at a rate . one surface of the wall ( 0) is insulated, and the other surface is exposed to a fluid at [infinity] 20°c, with convection heat transfer characterized by 2725 w/m2·k. initially, the temperature distribution in the wall is , where 300°c, -0.75 × 104°c/m2, and x is in meters. suddenly, the volumetric heat generation is deactivated ( 0 for 0), while convection heat transfer continues to occur at . the properties of the wall are 7000 kg/m3, 450 j/kg·k, and 90 w/m·k. while the wall experiences uniform volumetric heating, what is the value of the second derivative of temperature with respect to x evaluated at x = 0, in degree c/m^2? what is the heat generation rate per unit volume associated with the initial temperature distribution, in w/m^3? while the wall experiences uniform volumetric heating, what is the temperature of the wall surface at x = l, in degree c? while the wall experiences uniform volumetric heating, what is the value of the heat flux at x = l, in w/m^2? find the amount of energy removed from the wall per unit area after the heat generation is turned off and the wall cools from the initial temperature distribution to its final steady state temperature, in j/m^2.
