18. PLEASE ANSWER ASAP
The heat flux that is applied to one face of a plane wall is q 80 W/m2. The opposite face is exposed to air at temperature 30°C, with
a convection heat transfer coefficient of 20 W/m².K. The surface temperature of the wall exposed to air is measured and found to be
50°C. Assuming the area A = 1 m², determine the rate of energy storage in the wall per unit area, in W/m². Do steady-state
conditions exist? If not, is the temperature of the wall increasing or decreasing with time?
